Update Rbenv and ruby-build:
$ (cd ~/.rbenv ; git pull)
$ (cd ~/.rbenv/plugins/ruby-build ; git pull)
Install Rubinius:
$ rbenv install rbx-2.0.0
Add RBenv hooks to detect Rubinius gems by creating two files:
# in ~/.rbenv/rbenv.d/rehash/rbx-2.0.0.bash
make_shims "~/.rbenv/versions/rbx-2.0.0/gems/bin/*"
# in ~/.rbenv/rbenv.d/which/rbx-2.0.0.bash
if [ ! -x "$RBENV_COMMAND_PATH" ] && [[ $RBENV_VERSION =~ rbx-2 ]]; then
export RBENV_COMMAND_PATH="${RBENV_ROOT}/versions/${RBENV_VERSION}/gems/bin/${RBENV_COMMAND}"
fi
Install bundler:
$ gem install bundler
Go to your app and bundle!
$ cd ~/myapp
$ rbenv local rbx-2.0.0
$ bundle install
Ta-da!
