Switch from RVM to RBENV

rvm2rbenv.txt

## Prepare ###################################################################

# Remove RVM
rvm implode

# Ensure your homebrew is working properly and up to date
brew doctor
brew update

## Install ###################################################################
brew install rbenv
brew install ruby-build

## Config ####################################################################

# Global git ignore
git config --global core.excludesfile ~/.gitignore
printf "vendor/bundle\n.DS_Store\n" >> ~/.gitignore

# Set default bundle path
mkdir -p ~/.bundle
printf -- "---\nBUNDLE_PATH: vendor/bundle" >> ~/.bundle/config

# Instantiate rbenv with your shell (choose preferred file - .profile, .bash_profile, .zshrc, etc)
printf 'eval "$(rbenv init -)"' >> ~/.profile

# Remove the RVM stuff from your .profile - It probably looks like...
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

# Reload your profile
. ~/.profile

# Add autocompletion to IRB
touch ~/.irbrc
printf "require 'irb/completion'" >> ~/.irbrc

## Usage #####################################################################
rbenv

# Choose a ruby flavor version to install
rbenv install 1.9.3-p0
rbenv install 1.9.2-p290

# Rehash rbenv shims (run this after installing binaries)
rbenv rehash

# Set the global Ruby version and install bundler globally
rbenv global 1.9.3-p0
gem install bundler --pre
gem install OTHER_GLOBAL_GEMS # eg) Rails, Heroku, etc - NOTE: You need to do this for each ruby version.
rbenv rehash

# Set a project specific ruby version
cd myproject
rbenv local 1.9.2-p290

# Install gems in Gemfile to vendor/bundle
cd ~/projects/newhotness
bundle

# Start app in context of bundled gems
bundle exec rails s

## RubyMine Notes ############################################################
# Open settings | Ruby SDK & Gems
# Remove ALL RVM related SDK's
# Add new Ruby SDK for project - Find path by found by running `rbenv which ruby` in project directory
# Edit launch/debug configurations | Bundler - enable/check - Run the script in the context of bundler
# Note: RubyMine debugger will install some additional needed gems into your global gem path - eg) ~/.gem/ruby/...

Thanks so much!

Hello, you miss to set the PATH to rbenv in .profile.

$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.profile

That path isn't part of rbenv.

Don't need pre-release version of bundler

Thanks for this.

To avoid rehashing all of the time, have a look at https://github.com/sstephenson/rbenv-gem-rehash
