# ruby-build
ruby-build provides a simple way to build and install different
versions of Ruby on UNIX-based systems.
### Installing ruby-build
$ 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
setting the `PREFIX` environment variable.
### Installing Ruby
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
definitions](https://github.com/sstephenson/ruby-build/tree/master/share/ruby-build)
may be specified instead.)
$ ruby-build 1.9.2-p290 ~/local/ruby-1.9.2-p290
