Install the files
git clone git://github.com/jayferd/ry cd ry PREFIX=$HOME/.local make install
and add the following lines to your bashrc:
export PATH="$HOME/.local/bin:$PATH" eval "$(ry setup)"
or, if you don't like
eval, you can do it manually:
export RY_PREFIX="$HOME/.local" export PATH="$RY_PREFIX/lib/ry/current/bin:$PATH" . "$RY_PREFIX/lib/ry.bash_completion"
Ry is a bit different from other version managers. The major design goal of ry is to be explicit, unobtrusive, and easy to query. In the vein of the n package manager for node, there are no subshells, and the only thing it needs to add to your environment is a single entry to your
$PATH (also tab completion if you like). For example, here's how you create a new installation:
ry install http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p125.tar.gz mri-1.9.3
This creates an installation of Ruby called
mri-1.9.3 using the tarball from
ruby-lang.org. To switch to this ruby, use
ry use mri-1.9.3 # or: ry mri-1.9.3
Want to use a custom commit?
ry install https://github.com/ruby/ruby/tarball/<hash> mri-custom
If you have
ruby-build installed, you can use it very easily with ry:
ry install 1.9.3-p125
