Install RVM
Follow the latest instructions. Choose the non-sudo "single user install" unless you have a good reason not to.
Update RVM
rvm get stable
Installing Ruby
First, fix any dependencies listed here:
rvm requirements
Show installed rubies:
rvm list
Show all available rubies:
rvm list known
Install:
rvm install 1.9.3 # Latest known patch level rvm install 1.9.3 -j 3 # Parallel compile, set to # of CPU cores
Gemsets
rvm list gemsets # List rubies and gemsets rvm gemset list # List gemsets for current ruby
Create a new gemset:
rvm ruby-1.9.3-p194@rails2314 --create
Switch to a particular gemset:
rvm gemset use rails2314
Now you can use gem to install the needed gems.
May need to source /etc/profile.d/rvm.sh to get things working.
Project Setup and Best Practices
https://rvm.io//rvm/best-practices/
https://rvm.io/workflow/rvmrc/
cd ~/projects/my_project/ rvm --rvmrc --create 1.9.1@my_project
Now when you cd to the my_project directory, your ruby and gemset will change automatically:
cd ~/projects/my_project [ruby-1.9.1-p243] (0) $ ruby -v ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-darwin10.2.0] [ruby-1.9.1-p243] (0) $ gem env gemdir /Users/wayne/.rvm/gems/ruby/1.9.1@my_project
