How to remove a Yeoman generator

Question

I accidentally installed a generator that I don\'t want.
I can\'t find any method to remove it.
What should I do to accomplish this?

Answer 1

I wanted to add something for posterity:

If you get an number of errors of class 'peerDependencies' for yeoman's generators, updating yo alone will not cut it - you need to remove all generators that throw the error and then reinstall whatever module lead to the trouble.

Unfortunately, as far as I ahve chekced, regex is not supported by npm.
