'ng' is not recognized as an internal or external command, operable program or batch file

Question

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.

Answer 1

This error is simply telling you that Angular CLI is either not installed or not added to the PATH. To solve this error, first, make sure you’re running Node 6.9 or higher. A lot of errors can be resolved by simply upgrading your Node to the latest stable version.

Open up the Terminal on macOS/Linux or Command Prompt on Windows and run the following command to find out the version of Node you are running:

node --version

Answer 2

You can also try:

 > npm run ng <command>

Answer 3

I had the same issue on Windows7. 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 version
   

Also remember to install angular with -g command.

npm install -g @angular/cli

Answer 4

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.

Answer 5

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:

Answer 6

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!

Answer 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

Answer 8

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.

This answer is based on the following answer by @YuSolution https://stackoverflow.com/a/44622211/4567504.

In my case Installing MySQL changed my path variable and even after reinstalling @angular/cli globally many times I was not able to fix the issue.

Solution:

In command prompt, run the following command

npm config get prefix

A path will be returned like

C:\Users{{Your_Username}}\AppData\Roaming\npm

Copy this path and go to ControlPanel > System and Security > System, Click on Advanced System settings, go to advanced tab and select environment variable button like

Now in User Variables box click on Path row and edit and in variable value box paste your copied path.

Restart the command prompt and it will work

Answer 10

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

Answer 11

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

Answer 12

I have tried with this below Steps and its working fine:-

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.

Answer 14

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

Answer 15

npm update solves the issue for me

Answer 16

I just installed angular cli and it solved my issue, simply run:

npm install -g @angular/cli

Answer 17

This issue also bother me and then i find possible cases to reproduce this issue

when i run my window in administrator then it working fine ng but when i run this in my second space like other user then i got this issue.

so if i want to run my angular application then i need to run this command

npm run ng serve which is working but when i run the command with --host npm run ng server --host IP it not working given some error

so i find some possible solution 1. go appdata and then user\admin\AppData\Roaming\npm folder then copy this path but if you using other user account user\newuser\AppData\Roaming\npm folder you can copy this npm folder from other user i.e admin user account. if you do not want to copy this folder then copy the path of ****user\admin\AppData\Roaming\npm folder**** folder and then open your environment variable setting and add this path in path variable name

enter this path in system path variable not user variable C:\Users\admin\AppData\Roaming\npm

and run the command prompt as administrator then run ng command it will work

Answer 18

note: you may lose values once system restarts.

You can also add system environment variables without Admin rights in Windows 10.

now don't restart, close any opened cmd or powershell, reopen cmd and test by ng version command if you see this it is confirmed working fine.

hope this helps

Short answer:

Just install the latest version of nodejs and then restart your system.

It's related to Environment variables in your system at least as far as I know, you can make changes in path variable in your system as others talked about it in the current thread but the easiest way to solve this is installing nodejs!
