If you run the terminal in VSCode on Windows, and the command is not recognised, make sure that the Path environment variable includes the following path: C:\Users\user.name\AppData\Roaming\npm.

This can be determined by typing echo %PATH% in your terminal window, and comparing it with the external cmd.exe window.
