I’m trying to use RVM to install ruby 1.9.2 on a Lion system with xcode 4.2. I’m new to ruby so I don’t understand why this is not working. I’m reading Ruby on Rails 3 Tutorial as my install guide. However, book is not up to date as it relates to Lion. Can anyone point out what’s going on and give exact instructions on what I need to do?

    If you do a fresh install of Xcode 4.2, it does not come with GCC (it only comes with LLVM GCC). You should download: https://github.com/kennethreitz/osx-gcc-installer to get GCC.

    Once Xcode is installed:

    1. Install RVM (http://beginrescueend.com/rvm/install/)
    2. Close terminal, open a new terminal (just in case).
    3. Enter: rvm list known
    4. You can install any of the rubys with: rvm install X (where X is the ruby)
    5. If you’re not sure about step 4, just do “rvm install ruby-1.9.2”

    I think that’ll work…
