Can you give me some detail on how to reproduce this?

+1 Using v2.0.0 of yo and v1.3.6 of the generator on a Mac, I never managed to finish the generation process. I get to the components step where it always crashes with the exact same error as mentioned above. I tried several choices of components; also providing them as an command line option but the recipe still crashed at that point.

Same behaviour with yo v1.8.5

Can you tell me what parameters you are passing in? Give me an example command, for instance?

I could reproduce the same behaviour on a completely different machine with Windows.

So I just did this by hitting return at every option prompt (keeping everything default), and it seemed to work fine:

vagrant@homestead:~/webdev/craft/test$ yo craftplugin

Version 1.3.7 should fix this for you:
