"You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory"

Hi @mislav , I have a similar issue as This one.

I just noticed that you closed that issue so I open a new issue.

$ gem install bundler
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

I have added

eval "$(rbenv init -)"

to .bash_profile, and if I run

$ echo $PATH | tr ':' $'\n'

I got

/Users/username/.rbenv/shims
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

So you can see I have rbenv/shims at the highest. But when I run

which -a ruby

I got

/usr/bin/ruby

and with

which -a gem

I got

/usr/bin/gem

I don't know why they are still running. What I can tell is that under my .rbenv/versions or .rbenv/shims there is nothing there although I have run

brew install rbenv

I have also tried

rbenv local
rbenv global

which is suggested by other people. But the error remains. Do you have any idea on solving this?

Thank you in advance!
