My code was working previously before, but seems to have stopped working. I tried yo angular:route api but this error was returned:
Error: Cannot find module 'ansi-styles'

I have added all the dependencies required to my package file, update npm (which is now on 2.0.0alpha), all npm packages, and ran npm install. The site still works when I grunt serve.
回答1:
(The O.P.):
I found the reason I got the error. I had to change the npm root folder and reinstalled my packages in the default folder and now it works.
回答2:
Just needed to run npm install here. Was a fresh clone out of Git.
