ruby-build provides a simple way to compile and install different versions of Ruby on UNIX-like systems.
$ git clone git://github.com/sstephenson/ruby-build.git $ cd ruby-build $ ./install.sh
This will install ruby-build into
/usr/local. If you do not have
write permission to
/usr/local, you will need to run
sudo ./install.sh instead. You can install to a different prefix by
PREFIX environment variable.
To install a Ruby version, run the
ruby-build command with the path
to a definition file and the path where you want to install it. (A
number of built-in
may be specified instead.)
$ ruby-build 1.9.2-p290 ~/local/ruby-1.9.2-p290 ... $ ~/local/ruby-1.9.2-p290/bin/ruby --version ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.0.0]
You can use it with rbenv:
$ ruby-build 1.9.2-p290 ~/.rbenv/versions/1.9.2-p290
