How to get RVM to set correct gem path

Question

On a clean Mac OS X \"Snow Leopard\" install, I have a problem with RVM: It sets the Ruby path correctly but doesn\'t set the gem path. When I start a Rails server it mixes

Answer 1

Make sure you're always 'using' your Ruby version. (Ugh. RVM can be so annoying).

rvm use 1.9.3 --default

Also what does your .gemrc look like? I had to take out --user from mine.

Answer 2

So after 1 1/2 days of torture, reading through at least 50 posts, and installing RVM, Ruby and Rails multiple times, I am finally able to use Rails in my RVM install.

This was the last series of events that I did after installing RVM and Ruby the last time and then it worked:

I removed these from .gemrc so back up your file if you do this:

• gemhome: /home/[user]/ruby/gems
• gempath: []
• --remote

then use

rvm use 1.9.3 --default

then

gem install rails

It seems the trick was:

1. Change the .gemrc file.
2. Do not create and use a gemset (rvm use 1.9.3@rails3) before installing Rails.

Answer 3

Make sure you do a gem install rails after setting the default Ruby version:

  rvm use 1.9.2-head
  gem install rails

and then check again with which rails.
