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.
The Node version is 17.7.1. When I run npm -v I get:
bash: /usr/local/bin/npm: No such file or directory
But when I run npm root -g I get:
/usr/local/lib/node_modules
Running npm list -g also gives me the same message as running npm -v.
So, where is it supposed to be and how can I fix this?
There are a few issues as to why this is occuring.
It appears that your computer cannot find the following path (below) to the npm folder, but it can find the global node_modules folder.
/usr/local/bin/npm
This may occur for a number of reasons. Luckily, there are many solutions to these issues.
1. Reinstall Node.js and npm^
The first solution is pretty obvious, and it is to reinstall Node.js and npm^.
The installation process is very simple.
If you are using only the command line, you can install Node.js using the following command. The npm command comes installed with Node.js.
$ sudo apt-get install nodejs
Or, if you want to use the installer, download and run the installer from nodejs.org.
Check the versions of Node.js and npm to see if it has worked.
$ node -v
$ npm -v
The helpful thing about reinstalling Node.js and npm in this case is that, if Node.js and npm weren't installed in the first place (highly unlikely), it will install them.
However, if they were already installed, but then something happened to the installation directory (e.g. it was renamed, moved, deleted or corrupted), then the new installation will most likely have fixed that issue.
2. Add /usr/local/bin/npm to the path (solution worked for OP)
If the first solution didn't work for you, then the next issue that might be occurring might be that /usr/local/bin/npm isn't in your path, which means that bash cannot find it.
To add npm to your path, follow the steps below.
Normally, to get the path with npm, you need to run the following command.
$ npm bin
Obviously, we have to use a workaround. But, we can just use an assumed path for where the binaries of npm are stored, which is...
/usr/local/bin/npm/bin
However, this may vary, so, to be sure that this exists, you can simply type it into the command line.
$ cd /usr/local/bin/npm
Then, you can run the ls command, and see if there are any bin folders or .sh shell scripts that might be used for the path.
$ ls
Make sure you save the binary part for later!
Open the home directory using the following command. This is because the .bashrc file is in the home directory (used in the next step).
$ cd $HOME
Open the .bashrc file using vi (or any file editor of your choice, but vi will be used in this example).
$ vi .bashrc
Then, press the i key for Insert Mode. Type the following in the file.
export PATH=/usr/local/bin/npm/bin:$PATH
In vi, press Esc, then press the following keys: :, w, q, !, Enter.
:wq!
The file is now saved and the editor is closed.
Normally, the .bashrc file is only read when you log in each time. To avoid doing that, you can force bash to read the .bashrc file and update itself. To do this, run the following command.
$ source .bashrc
The bash shell should now be restarted.
These were quite a few steps (four, but many were compressed into one), but if a situation occurred where for some reason npm wasn't adding itself to the path, this solution should fix it.
3. Denied read/write access
Another issue is that your user profile doesn't have the right permissions to read/write to usr/bin/local/npm, or you didn't give npm permissions.
The fix to this solution is very simple.
Run the npm commands you want to run using sudo.
$ sudo npm -v
$ sudo npm list -g
If you want, you can make the commands you run automatically run with sudo.
$ sudo -s
$ npm -v
$ npm list -g
Warning: If you don't have the password for sudo, you can't run any of the commands using sudo above.
This should fix your issue, if denied read/write access is the problem.
There are most likely many more solutions^^, but they might be added later.
^ This is a very usual process, but it has to be added here so that I can be sure that this solution has been tried.
^^ These solutions may be found later and edited to this answer. Edited once.
use this command :
npm list -g
you should see your npm directory at first line
I tried to remove NPM and Node and reinstall them both. I'm a complete noob in the process as you'll notice.
I sadly can't remember the commands I used.
After I removed them, I ran node -v and it returned command not found and I ran npm -v and it returned command not found, so I thought the process was successful.
I then went to Nodejs website and downloaded the latest package for MacOS (v12.11.1) and ran the install. It said it was successful. I check node -v and it returned 12.11.1, as expected, but then I checked npm -v and it sadly returned npm not a command!!
If I run which node I get /usr/local/bin/node. If I run which npm I get nothing returned.
I've since tried lots of ways of removing them both again just in case something was missed but I get the same thing every time - no NPM!
Most of the answers on StackOverflow talk about Brew but I have not used Brew and I have tried so many of the other answers but just can't get NPM back.
The PKG installer mentions this: 'Make sure that /usr/local/bin is in your $PATH.' but not entirely sure what that means and if that's my problem or not.
Does anybody know a surefire way to remove all traces of both, so when I reinstall the PKG from Node, I get both Node and NPM installed and working correctly?
UPDATE:
I seem to have had some success since posting this question. I followed instructions at https://docs.npmjs.com/misc/removing-npm.html to manually remove 'everything NPM-rleated' and ran the installer again. Now when I check npm -v it returns to the latest version number 6.11.3.
I will test things a bit more before deleting/answering my own question.
To fix this problem I ran the following command as suggested by NPM:
To remove everything npm-related manually:
rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*
All was OK after I reinstalled Node and checked NPM's version using npm -v.
Googling 'Adding to $PATH mac' returns this as the top result:
https://www.architectryan.com/2012/10/02/add-to-the-path-on-mac-os-x-mountain-lion/
Open up Terminal and run the following command:
sudo nano /etc/paths
Enter your password, when prompted.
Go to the bottom of the file, and enter the path you wish to add.
Hit control-x to quit.
Enter “Y” to save the modified buffer.
That’s it! To test it, in new terminal window, type:
echo $PATH
this is what I did on mac
rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/npm*
brew uninstall node
brew install node
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 suipidly ran this script to stop having to use sudo on npm -g commands and now my node_modules are located at:
/Users/myusername/.npm-packages/lib/node_modules
when trying to run a commands i.e yo bower i get -bash: bower: command not found
Do I need to link this directory to the usr/bin?
In trying to sort this out I have run lots of commands and created symbolic links, I feel like my system is a real mess and I cannot really see what is going on? Help to ensure my system is clean would be really helpful.
Generally, it's a good idea to ensure that you do not need admin rights to run npm commands. The problem you're having, is that the directory where npm now installs its commmands (/Users/myusername/.npm-packges/bin) is not in your PATH. Your PATH is a list of directories where your shell searches for the commands you type.
You can add the directory to your path by adding the following line to the .bashrc file in your home directory (create it if it doesn't exist).
export PATH="${PATH}:/Users/myusername/.npm-packages/bin"
Open a new terminal, and bower should work again.
As an additional tip, I believe you're running on OS X? When installing Node.js using Homebrew, it is automatically installed in a proper way (no sudo needed to install packages globally and they will just work). Next time you're installing Node.js (or something else), Homebrew might be worth a try.
