These instructions explain how to migrate from rvm to rbenv.
Uninstall & Install
Start by executing the following command:
- Install rbenv
Follow installation instructions found here
- Install ruby-build
Follow instructions found here
- Install REE
ruby-build ree-1.8.7-2011.03 $HOME/.rbenv/versions/ree-1.8.7-2011.03
Need Ruby 1.9? Check which versions of Ruby rbenv supports with this command:
- Set global ruby
Edit ~/.rbenv/default and add:
You don't really need RVM gemsets as Bundler can install everything under your application directory. All you have to do is create the file ~/.bundle/config and put the following in it:
--- BUNDLE_PATH: vendor/bundle
This will tell bundler to install the gems in vendor/bundle instead of the global environment. Verify that the configuration is okay by executing the following command:
% bundle config Settings are listed in order of priority. The top value will be used. path Set for the current user (/Users/christian/.bundle/config): "vendor/bundle" disable_shared_gems Set for your local app (/Users/christian/Projects/xxx/.bundle/config): "1"
Create alias for 'bundle exec'
With RVM out of the picture you'll have to run commands with 'bundle exec'.
Add this to /.bash_profile\ or/.zsh/aliases:
alias b='bundle exec'
This will save you some typing by allowing:
b rails console # same as "bundle exec rails console"
* If you have issues compiling ree because of readline errors, make sure you have the latest version of ruby-build and then try specifying some options when compiling:
CONFIGURE_OPTS="-c --enable-shared -c --with-readline-dir=/usr/local/Cellar/readline/6.2.1/" ruby-build ree-1.8.7-2011.03 ~/.rbenv/versions/ree-1.8.7-2011.03
* System wide installation can be achieved as outlined in this gist.
