windows: npm: angular: 'ng' is not recognized as an internal command

 

>PROBLEM

Running the command "ng v", returns:

  'ng' is not recognized as an internal command

  'ng' não é reconhecido como um comando interno  (Portuguese)

>SOLUTION

This procedure is about Windows O.S.

After attempting to solve the problem through other experiences, I got no solution.

My Path seemed to be corrupted and there were no files under the user's folder, for instance at:

  C:\Users\<USER>\AppData\Roaming\npm\node_modules

So, to solve the issue, I decided to restart the environment installation from scratch.

This same procedure were executed several times, including restarting the sytem, until the success came. :-)

1. Uninstall node.js using the windows "Add remove application...".
   
   
2. Remove leftovers. Sometimes there are "skeleton" folder left behind. In my case, it was: C:\Users\<USER>\AppData\Roaming\npm\node_modules
   
   
3. Run the node.js as Administrator. Make sure of that, because it is important.
   
   
4. After the installation is fineshed, check it:
   node --version
   npm --version
   
   
5. Install @angular/cli that it is the lib that provides the "ng" command, as global installation (important: not locally).
   
   
7. The previous command will install the latest version. If you're working with a specific version, go to the angular project's root folder and check the package.json file to verify which version the project is working with: 
   "dependencies": {
    ...
    "@angular/cli": "^13.2.2",  
   ...
   
   
8. Under the project's root folder, install cli using the same version:
   npm install @angular/cli@13.2.2
   
   
9. Eventually, check it the project's env:
   ng v

It shall return the same version used for the project.
