Running windows 7 Professional 32bit.
I tried running npm install -g angular-cli both under normal or admin.
I also tried adding it to the Enviorment Variables under PATH: (C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng) , with no success also.
What am i doing wrong?
I solved this problem in accordance with the figure:
run in cmd
npm install -g #angular/cli
and then
( open in Windows 10) Control Panel\All Control Panel Items\System
or accordance with the figure
step 1:
step 2 :
step3:
step4:
step5: add missing ng path
Here is new environment variable that you need add: C:\Users\PK\AppData\Roaming\npm\node_modules\#angular\cli\bin
Finally, restart all opened command prompts and try again.
For me it works with:
npm run ng <command>
Adding C:\Users\DELL\AppData\Roaming\npm to System Variable Path worked for me. Please find your appropriate file path to 'npm'
Also, check if you have added your angular-cli\bin path to the path variable.
I am using WIN 10, just figure it out for this problem.
Type the code below in cmd:
npm config get prefix
and copy&paste the path that you get it from the top into your computer environment variables-->user variables box --> path --> edit -- C:\Program Files\nodejs\node_global, your path may different.
Click Ok and reopen your cmd window, type in ng version, then it works! Cheers!
Just open your command prompt (run as administrator). Ensure node --v is 6.9.0 or higher and npm --v is 3.0.0 r higher.
After that run the following command:
npm install -g #angular/cli
Once angular is installed. you can see an entry of angular cli in the path
C:\Users\Dell\AppData\Roaming\npm\node_modules\#angular
Then try ng help. It will work.
1) Enter below command on command prompt
npm install -g #angular/cli
2) Make sure that C:\Users\_username_\AppData\Roaming\npm this path is not hidden.
3) Add C:\Users\_username_\AppData\Roaming\npm and
C:\Users\_username_\AppData\Roaming\npm \node_modules#angular\cli\bin to both enviroment variable path.
4) Open new command prompt and type ng help. It will work.
With a command
npm install -g #angular/cli#latest
It works fine, I am able to run ng command now.
I solved it few days ago, after having the same problem with other global modules, by adding to:
Environment Tables -> System variables -> Path:
C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin;C:\Program Files\MongoDB\Server\3.2\bin
Note that it must not have any spaces after ;
That turned out to be my problem.
I followed below steps for resolution for this issue in Windows 10:
First make sure you have installed Angular CLI . You can use below
to install same.
npm install -g #angular/cli#latest
Make sure that AppData is visible and navigate to path below.
C:\Users\rkota\AppData\Roaming\npm
Same path can be found by running below too:
npm config get prefix
Add the above path i.e. " C:\Users\rkota\AppData\Roaming\npm" in Environment variable PATH and make sure it got added by running path in command prompt.
Close command prompt and now try to run below:
ng --version
you will be able to see CLI version.
execute following lines in order to solve the issue for both not found and undefined version of ng
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm cache clean
npm install -g #angular/cli#latest
Instead of using the in-built command prompt better start using the NodeJS installed version of command prompt. Then it is going to work perfectly without any issues.
General problem is that OS tries to find the PATH variable with ng keyword and cannot find it.
For me, even after the steps #behrouzmoslem suggested in the top answers to this post I didn't manage to get it work, because after the launch of ng command OS started to respond, but opens up editor file by the path C:\Users\{username}\AppData\Roaming\npm\node_modules\#angular\cli\bin\ng which is actually funny. So, solution is:
Just use npx before any angular executables.
Eg : npx ng serve for serving the angular app or npx ng build --watch to build with watcher.
If you get the error even after following the above step. then try below.
Since it is a node script. I am using the below option to create as of now.
node C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng version
May be symbolic links are required. Not researched further.
On Further Research:
Set Path as : %PATH%;C:\Users\Administrator\AppData\Roaming\npm;
In Windows, npm.cmd file is in the above path. If the above Environment variable is set, you can execute as
ng version
ng init
Open cmd and type npm install -g #angular/cli
In environment variables, add either in the user variable or System variable "Path" value=C:\Users\your-user\.npm-packages\node_modules\.bin
In cmd: c:\>cd your-new-project-path
...\project-path\> ng new my-app
or ng all-ng-commands
I resolved by adding - %AppData%\npm\node_modules#angular\cli\bin\ path to my environment variables path
close cmd and open it again with admin right or reboot ur system.
for me it works only with the flag --force:
npm install -g #angular/cli --force
If everything is fine then you shoud see the folder node_modules in this path:
C:\Users\YOUR_USERNAME\AppData\Roaming\npm\
I faced same issue when i tried to install angular cli locally with command
npm install #angular/cli#latest
After that i got same issue
C:\Users\vi1kumar\Desktop\tus\ANGULAR\AngularForms>ng -v
'ng' is not recognized as an internal or external command,
operable program or batch file
Than i tried to install it globally
npm install -g #angular/cli#latest
In this case it worked I was wondering that is it not possible to install cli globally ?
After doing some research I found this article very helpful hope it will help someone facing similar issue
Working with multiple versions of Angular CLI
This one almost worked for me, but I had to use: %USERPROFILE%\AppData\Roaming\npm
. In Environment Variables.../System variables/Path
Then when I did CMD: "ng -v" I got the correct response for angular cli.
npm install -g #angular/cli helped for me instead of npm install #angular/cli
1- Install
$ npm install -g #angular/cli
2- Make sure where your ng.cmd is present.
3- Then add this path into variables.
I had the same problem on Windows 7, 64 bits running with npm v3.10.8.
I added the path as it was suggested: ( C:\Users.....(your user name)\AppData\Roaming\npm\node_modules\angular-cli\bin\ng) and uninstalled angular-cli.
After this, I cleared the npm cache by npm cache clean as prompted here https://blogs.msdn.microsoft.com/matt-harrington/2012/02/23/how-to-fix-node-js-npm-permission-problems/. This guarantees there are no leftovers.
Reinstalled angular-cli with npm install -g angular-cliand voila.
Hope that may be useful!
In my case I did below steps.
All Programs -> Node JS-> Right click on Node.js Command Prompt and select properties and from Target string at end copy below
/k "C:\Program Files\nodejs\nodevars.bat"
I launched Visual Studio Code and opened below file
C:\Users\gochinta\AppData\Roaming\Code\User\settings.json and gave below
// Place your settings in this file to overwrite the default settings
{
"terminal.integrated.shellArgs.windows":
["/k", "C:\\Program Files\\nodejs\\nodevars.bat"]
}
Now I typed ng -v in my Visual Studio Code Terminal window and it worked.
I was having the same issue when tried with the syntax "ng new " and solved that simply by updating the existing node version from 5.x.x to 8.x.x. After successful updation of node, the syntax worked perfectly for me. Please update the existing version of node. As it is clearly mentioned in angular documentation that these commands require the node version >= 6.9.x. For reference please check https://angular.io/guide/quickstart. It clearly states "Verify that you are running at least node 6.9.x and npm 3.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors, but newer versions are fine".
I faced same issue on x86, windows 7;
uninstalled #angular/cli
re-installed #angular/cli
checked & verified environmental variables (no problems there)...
Still same issue:
Solution was the .npmrc file at C:\Users{USERNAME}... change the prefix so that it reads "prefix=${APPDATA}\npm"... Thanks to this website for help in resolving it
For me something was wrong in the PATH enviroment variable. I removed all path related to npm and added at the start of PATH this folder:
c:\Users\<your-user-name>\AppData\Roaming\npm\
Make sure you have ; between paths.
I am facing same issue and it's get resolved. At my end reason is i install node and CLI using other user profile and now i am running ng command from other user login. Since node and cli installed using other user login node is not finding anything on C:\Users\<user name>\AppData\Roaming this path and that's why i am getting this error.
I run npm install -g #angular/cli command and restart my machine. Every thing is working fine.
Sometime in the future. Applicable to Windows 8.1 machine.
Run the following commands
npm install -g #angular/cli
Log out or restart your machine.
This should add the required env path, rather than doing it manually.
I also tried to play with cmd by setting environment variable path & etc, but simple answer is use nodejs command prompt.
So you no need to set environment variable path or anything. When you insalled nodejs it will give it's command prompt, by using that you us "ng" command, without any settings.
Since this question is still asked over and over again one year later I will post my answer here as well.
The clue (on Windows only) is to arrange the entries in the path variable right.
As the NPM wiki tells us:
Because the installer puts C:\Program Files (x86)\nodejs before C:\Users\\AppData\Roaming\npm on your PATH, it will always use version of npm installed with node instead of the version of npm you installed using npm -g install npm#<version>.
So your path variable will look something like:
…;C:\<path-to-node-installation>;%appdata%\npm;…
Now you have two possibilities:
Swap the two entries so it will look like
…;%appdata%\npm;C:\<path-to-node-installation>;…
This will load the npm version installed with npm (and not with node) and with the installed Angular CLI version.
If you (for whatever reason) like to use the npm version bundled with node, add the direct path to your global Angualr CLI version. After this your path variable should look like this: …;C:\Users\<username>\AppData\Roaming\npm\node_modules\#angular\cli;C:\<path-to-node-installation>;%appdata%\npm;…
or …;%appdata%\npm\node_modules\#angular\cli;C:\<path-to-node-installation>;%appdata%\npm;…
for the short form.
This worked for me since a while now.
While logged in to Windows 10 as a User, and opened the command prompt as an Adminstrator, cd to my nodeJs project directory and did npm install browser-refresh -g in order to install the browser-refresh package from the npm which went ok but with some "npm WARN deprecated" messages. and the confirmatioin
browser-refresh#1.7.3
then I modified my code according to the package instructions and did browser-refresh index.js which suppose to replaces node index.js but I get the error
'browser-refresh' is not recognized as an internal or external command, operable program or batch file.
So I installed it locally with out the -g tag for no avail. I able to run it using the command C:\Users\adminName\AppData\Roaming\npm\browser-refresh index.js
I added the path above to the list of Paths under "System variables > Path" for no avail. I may un install the local package since that did not work. Someone please suggests a working solution.
Even though I get it running with the long command, the pacakge did not refresh the web page after changed the index.html file and saved it but this may be a different question.
Thank you
The path to the NPM bin folder may not be defined in your PATH environment variable. You can test this by installing another package that should be executable from the command line and checking to see if executing it results in the same error.
If it does, you can "%AppData%\npm" to your PATH. Here are instructions on how to do so.
Hope this helped!
I am trying to use Gulp and Node.Js to stream my process for minifying and concatenating CSS/JS files for production.
Here is what I have done.
I installed Node.Js on my Windows 7 machine.
Installed Gulp globally using this command npm install -g gulp
Then I added a new User variable called NODE_PATH set it to %AppData%\npm\node_modules
After closing and re-opening my command line, I tried to run a gulp task from the command line (i.e. gulp css). But that give me the following error
'gulp' is not recognized as an internal or external command
How can I get this to work?
When I opened the following path using the search bar in windows,
%AppData%\npm\node_modules I see the following two folders
gulp
gulp-cli
I've tried to add %AppData%\npm\node_modules to the Path variable on my system variable, but it did not take it because that variable reached it's max allowed character limit.
I removed couple of paths from my Path variable and added ;C:\Users\[MyWindowsUserName]\AppData\Roaming\npm\node_modules
but still not working.
I even tried to set the path at run time using this command
PATH=%PATH%;C:\Users\[MyWindowsUserName]\AppData\Roaming\npm\node_modules
then run gulp and still the same issues.
What am I missing here? What else do I need in order to get this to work?
I had similar issue when I installed locally initially(w/o -g). I reinstalled with -g (global) and then it worked.
npm install -g gulp
you should run gulp from folder where gulpfile.js is available.
I solved the problem by uninstalling NodeJs and gulp then re-installing both again.
To install gulp globally I executed the following command
npm install -g gulp
Go to My Computer>Properties>Advance System Settings>Environment Variables>
Under the variables of Administrator edit the PATH variable & change its value to "C:\Users\Username\AppData\Roaming\npm". Note: The username in the path will be the current Admin user's name that you have logged in with.
I had the same problem on windows 7. You must edit your path system variable manually.
Go to START -> edit the system environment variables -> Environment variables -> in system part find variables "Path" -> edit -> add new path after ";" to your file gulp.cmd directory some like ';C:\Users\YOURUSERNAME\AppData\Roaming\npm' -> click ok and close these windows -> restart your CLI -> enjoy
You may need to install the gulp-cli globally. Uninstall then re-install if you already have it:
npm uninstall -g gulp-cli
npm install -g gulp-cli
Sorry that was a typo. You can either add node_modules to the end of your user's global path variable, or maybe check the permissions associated with that folder (node _modules). The error doesn't seem like the last case, but I've encountered problems similar to yours. I find the first solution enough for most cases. Just go to environment variables and add the path to node_modules to the last part of your user's path variable. Note I'm saying user and not system.
Just add a semicolon to the end of the variable declaration and add the static path to your node_module folder. ( Ex c:\path\to\node_module)
Alternatively you could:
In your CMD
PATH=%PATH%;C:\\path\to\node_module
EDIT
The last solution will work as long as you don't close your CMD. So, use the first solution for a permanent change.
In my case, this problem occured because I did npm install with another system user in my project folder before. Gulp was already installed globally. After deleting folder /node_modules/ in my project, and running npm install with the current user, it worked.
You need to make sure, when you run command (install npm -g gulp), it will create install gulp on C:\ directory.
that directory should match with whatver npm path variable set in your java path.
just run path from command prompt, and verify this. if not, change your java class path variable wherever you gulp is instaled.
It should work.
If you have mysql install in your windows 10 try uninstall every myqsl app from your computer. Its work for me. exactly when i installed the mysql in my computer gulp command and some other commands stop working and then i have tried everything but not nothing worked for me.
I just encountered this on Windows 10 and the latest NodeJS (14.15.1). In my case our admins have our profiles and true "home" folder remotely mount onto our work machine(s). Npm wanted to put its cache over on the remote server and that has worked until this release.
I was unaware that npm has a .npmrc file available. I added one to my actual machine's C:\Users\my-id folder and it contains:
prefix=C:\Users\my-id\nodejs\npm
cache=c:\Users\my-id\nodejs\npm-cache
I also added these paths to my PATH environment variable.
I went to the APPDATA folder on my work machine and the remote "home" server and deleted all the npm related Roaming folders. I deleted the node_modules folder in my project.
I closed all open windows and reopened them. I brought up a command prompt in my project dir and re inited npm and reinstalled the modules I wanted.
After that everything is rolling along.
Just to add to #Vinod R's answer
Go to My Computer>Properties>Advance System Settings>Environment Variables>
Under the variables of Administrator edit the PATH variable & change its value to "C:\Users\Username\AppData\Roaming\npm". Note: The username in the path will be the current Admin user's name that you have logged in with.
After this, move the path to the top as shown in the image attached.

I was having the same exception with node v12.13.1,
Downgraded node to v10.15.3 and it works fine now.
The best solution, you can manage the multiple node versions using nvm installer. then, install the required node's version using below command
nvm install version
Use below command as a working node with mentioned version alone
nvm use version
now, you can use any version node without uninstalling previous installed node.
I'm trying to run karma as part as an angular-seed project, after installing karma using
npm install -g karma
I get:
'karma' is not recognized as an internal or external command, operable program or batch file.
when i'm trying to run test.bat from angular-client\scripts, the content of this file is:
set BASE_DIR=%~dp0
karma start "%BASE_DIR%..\config\karma.conf.js" %*
I also tried to navigate to "\AppData\Roaming\npm\node_modules\karma\bin" and saw karma file, when I'm trying to run it I get again:
'karma' is not recognized as an internal or external command, operable program or batch file.
Any suggestions?
If not please suggest how to use jasmine without karma.
Thanks.
The command line interface is in a separate package.
To install this use:
npm install -g karma-cli
karma-cli
It is recommended to install karma with its Command-Line-Interface (karma-cli) which will take care of fetching the appropriate karma. You can also install a different local version specific to each project you're working on and karma-cli will pick the appropriate one.
From the karma installation page:
Typing ./node_modules/karma/bin/karma start sucks so you might find it useful to install karma-cli globally:
npm install -g karma-cli
Now, check that karma was installed by typing:
which karma //echo something like: /usr/local/bin/karma
and check that karma server is working (ctr+c to quit):
karma start
You can also check that karma was installed by going to this directory:
cd /usr/local/lib/node_modules/karma
Good luck!
On windows when you install a npm (non-globally - so without the -g flag), the executable commands are linked in the node_modules\.bin folder.
For example:
powershell> .\node_modules\.bin\karma start
powershell> .\node_modules\.bin\karma run
I had the same issue and fixed it by correcting my PATH environment variable.
STEP 1: go to the following path and ensure karma.cmd is present at the location given below
[Nodejs folder path]\node_modules\.bin <=> C:\Program Files\nodejs\node_modules\.bin
STEP 2: If present go to STEP 3, If not present run the following command npm install -g karma
STEP 3: Open environment variables and edit PATH
STEP 4: Add the following at the end :
[Nodejs folder path]\node_modules\.bin; <=> "C:\Program Files\nodejs\node_modules\.bin"
Log out your session and it will work for sure.
Based upon your directory using \AppData\Roaming, you're on Windows and this error is usually because the path to the npm globals isn't in the Windows PATH or NODE_PATH environment variables.
Use SET to check the values you are using for the paths and if your npm directory isn't listed, that will be the issue.
If you don't want npm to save to this directory, check the npm configuration options and the npm folders docs to see what you can change in this regard...
'karma' is not recognized as an internal or external command, operable
program or batch file.
If the above mentioned solution does not work, than
The cause of issue is previous version of nodejs. So uninstall the previous version of nodejs and re-install the latest version. It will resolve your issue. As I faced the same and by doing above changes it worked for me.
Thanks.
Official documentation at https://karma-runner.github.io/0.12/intro/installation.html is confusing. It implies that npm install -g karma-cli is to install karma globally but it actually required for to run karma from command line.
I had same: 'karma' is not recognized as an internal or external command, operable program or batch file. problem when i tried to install it directly to my project file. When i used npm install -g karma-cli to global install everything worked just fine.
Okay I am running node on windows (7). Using npm I just installed modules to d:\ directory. Therefore my files structure looks like the following:
D:\
-myproject
-node_modules
-.bin
-express
However, when I am in this 'myproject' directory, I can't seem to run 'express' for example:
D:\myproject\express site
'express' is not recognized as an internal or external command, operable program or batch file.
Am I doing anything wrong?
Try:
npm install -g express-generator#3
That solved problem for me.
Edit: for version 4
npm install express-generator -g
Description:
express is the package for dependency of express js.
express-generator is the package for enabeling express command and create a sample project, etc.
Assuming that this is kept separate for the decoupling of project dependency with cli tool of express.
Another SO ref: https://stackoverflow.com/a/41311733/1666582
Here's what to type in the command line to make it work in windows:
npm install express-generator -g
[Source: http://expressjs.com/starter/generator.html]
My guess is that you didn't install Express globally. You can install express globally (and therefore available in your PATH) with the following command (see http://expressjs.com/guide.html) :
npm install -g express
The way you install it is available only in the folder that you installed it and there is nothing wrong with that approach. There is very little advantage of having it available globally.
If express is not in your PATH you can run it by entering the full path to it:
\myproject\node_modules\.bin\express.cmd
With the release of Express 4.0.0 it looks like you need to do
npm install -g express-generator
We need to set path for express global directory
C:\Users[User_Name]\AppData\Roaming\npm\
After add a new path, please reopen the CMD console
Tried all of these and never worked. A repair of Node.js by kicking of installation and selecting repair option does the magic.
Cheers
What worked for me was:
I used the windows command prompt instead of the node.js command prompt.
In windows 10 simply type in the windows search bar for "node"
You see a node.js desktop app and a node js command prompt.
Choose the "node js command prompt"
Type in the command prompt
npm install express-generator -g
Then navigate somewhere and type in:
express your-website-text-here -e
A directory with express files will be generated. Also now you won't see the express error.
I was able to fix with the following package install:
npm install express-generator -g
Thanks
When you install Node.js, the below path is added to the Windows OS %Path% variable, I'm presuming similar happens on other operating systems as well:
C:\Users\<your-windows-username>\AppData\Roaming\npm
In my case, because I use a work Windows laptop for an employer that severely restricts what employees can do on their machines (I.e. many actions require elevated admin privileges), Node.js was being prevented from adding the above path to the Windows %Path% environment variable, and much to my chagrin the Node.js installation was silent about it. Navigate to above folder and you will notice the express command lives there, see screenshot below.
How did I figure this out? I did a fresh installation of Node.js on a personal, home Windows machine that has no admin privilege restrictions like my work machine does, compared the before and after %Path% value, and noticed the addition of that path. My work machine was missing it.
I had no choice but to add the path manually to %Path%, and then express was recognized from within any path I ran it.
I was able to fix this with:
npm install express-generator -g
I tried all the above solution, no luck for me.
Open "Node.js" command prompt and tried as administrator. It is working fine for me. Don't try with windows command prompt.
I have the same problem and understand the solution, but i can´t undestand why, running npm install -g express, express.bat isn´t added automatically to Path.
Running with npm install -g express have the same result. Download packages and store in node_modules, but express.bat isn´t added to path.
Run the node command prompt as administrator and then install express globaly
npm install -g express
and then go to folder where you want to install express generator, open command prompt there and run this command
npm install express-generator, it will then fix the issue
I have tried out all above solutions, but its did't worked for me, finally I have re-installed the node.js with newer version and started to express install process again. Its worked for me.
npm install -g express
npm install -g express-generator
What command are you using to open the directory?
That error means CMD can't find the "express" executable in the current directory.
Use the "PUSHD" command or "CD /D" instead of "CD"
#Echo OFF
PUSHD "D:\myproject\express" || (Echo bad folder)
express.exe "site"
Pause&Exit
Express is loaded someplace else and not in the windows path environment variable. You need to find were express.exe is installed and add the path. Maybe something like ;"C:\Program Files\Express\bin";
Running "npm install express" and "npm install express-generator" from your project directory will resolve the issue (if that helps).
But, this doesn't solve the problem of being global.
You might check the permissions to the folder if you are getting this when creating your project
Express Project
change script section in package.json file like this
"scripts": {
"start": "node app.js"
}
I too faced the similar problem and at last I tried using node.js command prompt instead of windows command prompt and it worked. So, try from node.js command prompt.
Tried all of these but didn't work for me. Also, I tried from different sources but never worked for me.
In the end, found that I need to run the command forcefully. It worked for me.
Make sure you run the command with Run as Administrator.
npm install -g --force express-generator
It will overwrite the existing express files.
Use npm start .. then the app.js runs .. which can be listened on the usual port 3000
