Uninstalling rails and gems, getting error "cannot uninstall, check 'gem list -d …?

SOLUTION! I still don't understand why this happened, I'd love if someone could explain. Why was the path non-existant?

What caused this error?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
