'ng' is not recognized as an internal or e

问题:

I tried running npm install -g angular-cli

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.

回答1:

Use NodeJS command prompt rather Windows Command, NodeJs command prompt will recognize ng.

回答2:

You can also try:

 > npm run ng <command>

回答3:

You should not add C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng to your PATH. There is only a javascript file which you cannot use in terminal.

You need ng.cmd which is probably located at %AppData%\Roaming\npm. Make sure this path is included in your PATH variable.

回答4:

I had the same issue on Windows 7. I resolved it setting correct path.

1. First find ng.cmd file on your system. It will usually at:

   E:\Users\<username>\AppData\Roaming\npm
   

2. Set PATH to this location.

3. Close existing command window and open new one

4. Type

   ng -v
   

Also remember to install angular with -g command.

npm install -g @angular/cli

回答5:

You should add the path where ng.cmd located. By default, it should be located on C:\Users\user\AppData\Roaming\npm

NB: Here "user" may vary as per your pc username!

I was with the same problem and now discovered a working solution. After successful installation of node and angular CLI do the following steps.

Open C:\usr\local and copy the path or the path where angular CLI located on your machine.

Now open environment variable in your Windows, and add copied path in the following location:

Advanced > Environment Variable > User Variables and System Variables as below image:

That's all, now open cmd and try with any 'ng' command:

回答7:

make sure environment variables are set properly.

control panel-> system->advanced system settings-> select advanced Tab->
click on environment variables

and make sure in the path below line is available

`C:\Users\username\AppData\Roaming\npm`   

here username will get changed based on the user

.

still if its not working yourenvironment variables are not getting reflected so please restart your machine it will work fine

if still you are facing issue your angular cli is not installed properly

please run below commands for reinstalling

   npm uninstall -g @angular/cli

    npm cache clean    or   npm cache clean  --force

    npm install -g @angular/cli@latest

回答8:

If angular cli is installed and ng command is not working then please see below suggestion, it may work

In my case problem was with npm config file (.npmrc ) which is available at C:\Users{user}. That file does not contain line registry https://registry.npmjs.org/=true. When i have added that line command started working. Use below command to edit config file. Edit file and save. Try to run command again. It should work now.

npm config edit

回答9:

Just adding a little info to the previous answers, If you have windows 7 or above then go to start and search Node.js command prompt and you will be directly shown the app. Click on it, and start working by using that command prompt for angular.

回答10:

You don't need to set any path. Follow the below step to resolve the problem-

Step 1- go to

C:\Users\user\AppData\Roaming and delete npm, npm-update and npm-cache folder

Step 2- run

npm install -g @angular/cli@yourangularversion again.

回答11:

What worked for me was that I was missing an file

.npmrc

which is located under

C:\Users\username

That file should contain

prefix=$(APPDATA)\npm

Also my environment path was pointing to my admin user

回答12:

No need to uninstall angular/cli.

1. You just need to make sure the PATH to npm is in your environment PATH and at the top.

C:\Users\yourusername\AppData\Roaming\npm

2. Then close whatever git or command client your using and run ng-v again and should work
