Switched my shell to fish and now rails wont load a server. How can I get it running?

Question

Ok, well I just changed my shell to use fish instead of oh-my-zsh. I removed oh-my-zsh and everything got a bit messed up. So I installed rails and bundle installed my application, but i'm getting this error when I try to load the server.

It's pointing /Library/Ruby/Gems/2.0.0/gems/ here, but I use rbenv. I'm not sure if it should be looking inside of rbenv.

D-side gave this link above in a comment.

https://github.com/sstephenson/rbenv/issues/195

adding these shims to my config.fish fixed the problem:

set PATH $HOME/.rbenv/bin $PATH
set PATH $HOME/.rbenv/shims $PATH
rbenv rehash >/dev/null ^&1
