Question

I\'ve just gone to installed RoR on my snow leopard mac.. and found the rails gem was already installed..

is this normal? Does it need updating?

Does this get in

Answer 1

I found an incredibly well written install guide at The Pragmatic Studio called Installing Ruby 1.9 and Rails 3 on Mac OS X. It took about an hour to follow, including installing several prerequisites.

I'm hesitant to mess too much with OSX's native installation of ruby/rails, lest things get broken by an Apple system update, so I was very excited to learn about RVM (Ruby Version Manager) which is a cool tool for switching between different ruby/rails installations. The Pragmatic Studio tutorial walks you through installing rvm.

There are a few glitches with the guide, which I'll list here:

• Git: I just installed git itself. You do not need to set up a github account.
• Git: You may need to manually add /usr/local/git/bin to your PATH. (They don't explicitly tell you to)
• RVM: The protocol for the rvm-install-head URL should be https, not http
• RVM: The installer complained a lot, but it worked anyway.
• RVM: The newly installed ruby 1.9.2 didn't activate until I ran 'rvm 1.9.2' in step 8

All told, this seems like a GREAT approach, and I'm really impressed with their install guide!
