Did you properly install your NodeJS and installed the Cordova CLI using:
[crayon-660688022e35a837454638/]
If you restart your Terminal and try the CLI simply by typing
[crayon-660688022e36c883419840/]
and all you get is a lousy
[crayon-660688022e36e831020862/]
This issue is probably caused by the PATHS not being configured right by the NodeJS install.
Just dive into your /etc/paths file and add the following directories:
[crayon-660688022e370192655529/]
Once youv’e saved the file and restarted your Terminal go ahead and check how the Cordova CLI smiles at you 🙂
