I am using node version 6.9.2 with npm version 5.4.2 on Windows7. I have installed typescript with the command npm install typescript -g.
However, when I run a demo file using command, tsc, I get an error:
"tsc is not recognized as an internal or external command".
Could anybody help? Other node modules get installed correctly and working fine. Not sure why typescript isn't working.
The problem is likely that tsc is not in the system path.
First, check if tsc is installed correctly. Open cmd.exe and type the following.
%AppData%\npm\node_modules\typescript\bin\tsc --version
If there is a version log, then tsc is installed successfully.
The next thing is to add it in PATH. Write in cmd.exe
setx path "%path%;%AppData%\npm\node_modules\.bin\"
This should solve the issue.
However, if the first command did not log the version,
Check the install location using
npm list -g
If typescript appears in the output, copy the location to the PATH as
setx path "%path%;<--the tsc.exe path-->"
Hope this helps.
Since you installed it globally and you had no error, I can assume that the installation succeeded.
To be sure, you can run this command npm config get prefix. It will output the path of the folder containing all packages installed globally by npm. I you go to the folder specified by the path, there is a nodes_modules subfolder. It should contain a typescript folder if the installation succeeded. Then copy the path of the bin of the typescript folder in your environment variable. You should label the path tsc.
Then you can use tsc in command line.
I found this solution in this website and it worked for me.
-> If you are on windows and getting this error "'tsc' is not recognized as an internal or external command."
Solution
-> add the following path "C:\Users\user\AppData\Roaming\npm" to the PATH variable replace user with your windows user.
-> Restart the System.

What is npm?
Whenever I browse through some project they ask me to run npm command, something like this
npm install -g node-windows
I went through some blog posts to learn about npm and I installed Node.js. However, when I run the above code in Node.js, I get the following errors:
When I browsed further, I came to know that the windows user can run the command from the cmd prompt window, but when I do that I get some output like this:
Which just generate a text file nothing else.
My questions:
How can I get started with the AngularJS2?
How can I run an npm command?
Do I require a command prompt to run the npm command (in Windows), or I can just use Node.js?
When I use the command npm install in my command prompt, I get the following output:
How to get started with the angularJS2
Follow this link and set up the project by following instructions
How to run a npm command
npm stands for Node Package Manager, and therefore you need Node.js installed before you can run npm commands.
Follow this and install the latest version. And restart the command prompt.
Do I require a command prompt to run npm commands (in Windows), or can I just use Node.js?
Yes, you need to run npm commands from the command line (in Windows).
E.g., npm install
You get the warning because there is no package.json file present where you are running the command.
ENOENT stands for Error NO ENTrey
Navigate to the project folder using the following command and then run npm install
cd <projectpath>
The AngularJS 2 website has everything you need to be covered. Their quickstart guide alongside with the quickseed zip file helps a lot.
But, in case you missed some points:
yes, you will need npm/NodeJS. So, download the latest distribution and have a clean installation of it.
you can execute the npm command with its parameters from within the Windows cmd.
the quickseed ZIP file contains all the files you need to see a live and quick example running locally. Unzip it on your workplace and navigate to it using the windows cmd. When inside the root folder of the unzipped package, execute npm install and right after it npm start.
Take the learning path. Step by step, all your questions will be answered.
You need to use an admin prompt for global installation (-g).
I am new to node.js. I downloaded and install node.js installer from the official site. I have added this installer folder in PATH environment variable and I am able to run programs. But when I try to install some package using npm in node console it shows the error npm should be run outside of the node repl, in your normal shell. I also tried it on a separate console. But it shows command not found though I have added node in the environment variable.
For Windows users, run npm commands from the Command Prompt (cmd.exe), not Node.Js (node.exe). So your "normal shell" is cmd.exe. (I agree this message can be confusing for a Windows, Node newbie.)
By the way, the Node.js Command Prompt is actually just an easy shortcut to cmd.exe.
Below is an example screenshot for installing grunt from cmd.exe:
Do not run the application using node.js icon.
Go to All Programmes->Node.js->Node.js command prompt.
Below is example screen shot.
If you're like me running in a restricted environment without administrative privileges, that means your only way to get node up and running is to grab the executable (node.exe) without using the installer. You also cannot change the path variable which makes it that much more challenging.
Here's what I did (for Windows)
Throw node.exe into its own folder (Downloaded the node.exe stand-alone )
Grab an NPM release zip off of github: https://github.com/npm/npm/releases
Create a folder named: node_modules in the node.exe folder
Extract the NPM zip into the node_modules folder
Make sure the top most folder is named npm (remove any of the versioning on the npm folder name ie: npm-2.12.1 --> npm)
Copy npm.cmd out of the npm/bin folder into the top most folder with node.exe
Open a command prompt to the node.exe directory (shift right-click "Open command window here")
Now you will be able to run your npm installers via:
npm install -g express
Running the installers through npm will now auto install packages where they need to be located (node_modules and the root)
Don't forget you will not be able to set the path variable if you do not have proper permissions. So your best route is to open a command prompt in the node.exe directory (shift right-click "Open command window here")
It's better to use the actual (msi) installer from nodejs.org instead of downloading the node executable only. The installer includes npm and makes it easier to manage your node installation. There is an installer for both 32-bit and 64-bit Windows.
Also a couple of other tidbits:
Installing modules globally doesn't do what you might expect. The only modules you should install globally (the -g flag in npm) are ones that install commands. So to install Express you would just do npm install express and that will install Express to your current working directory. If you were instead looking for the Express project generator (command), you need to do npm install -g express-generator for Express 4.
You can use node anywhere from your command prompt to execute scripts. For example if you have already written a separate script: node foo.js. Or you can open up the REPL (as you've already found out) by just selecting the node.js (start menu) shortcut or by just typing node in a command prompt.
As mscdex said NPM comes with the nodejs msi installed file. I happened to just install the node js installer (standalone). To separately add NPM I followed following step
Download the latest zip file of NPM from here.
Extract it in the same file as that of node js installer.
If you have added the directory containing to node js installer to PATH env variable then now even npm should be a recognized command.
you just open command prompt,
then enter in c:/>('cd../../')
then npm install -g cordova
It's simple. Press the Windows logo on your keyboard. Then, type node.js command prompt in the search bar and run it.
You must get directory right path of program(node.js in program files).
such as
and use "npm install -g phonegap"
Just open Node.js commmand promt as run as administrator
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
