Gem permission issues with rbenv running?

I am using Rbenv to manage my ruby versions, and don't remember ever having an issue before. It's been a while since I developed at home though.

Basically this is what happens:

➣ gem install rails
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
➣ rbenv local
2.3.1
➣ rbenv global
2.3.1

Really not sure what I'm missing. Never seen this issue before.

Solution

  • @rPat, what does the command

    $ which gem

    reveal? If it indicates you're using the the system gem command, try

    $ rbenv rehash

    and see if that resolves the issue.

    Also make sure

    eval "$(rbenv init -)"

    is in your .bash_profile
