Solution

Thanks to everyone who responded, after a few tweaks I’m done being able to correct.

The name of the varial Path for PATH.

Then add the path C:\Users\USUARIO\AppData\Roaming\npm.

I restarted and ran the Tsc and ng commands again

Answer 1

In Windows, add in the environment variables, adding in the PATH variable the value below:

%AppData%\npm;

Save, close the terminal cmd or cmder or Powershell, and try to run the command ng again.

You may have to log in to Windows again.

Inform if it worked.

Answer 2

Are you using standard Windows CMD or Power Shell? Sometimes use Cmder or even git bash solves... or maybe use the VS Code.
