Add checks for multiple yo versions #30
Description
I've seen this issue a few times. Basically the user have a yo version installed, and their npm now install in a different binary folder. This cause an issue where the user always use the old yo version as their new ones is not found on their path.
I'm unsure how we could detect this, but the issue is clear when you check where npm installs modules against what is returned with which yo (where yo on windows)
