'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

Answer 1

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

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:
