rbenv from rvm with Homebrew

gistfile1.md

• $ rvm implode to remove rvm completely, thanks Wayne.
• $ brew install rbenv to get the new hawtness!
• $ brew install ruby-build to allow us to install Rubies (rbenv doesn't have an install command).

to ignore the version files rbenv makes add this to ~/.gitconfig_global .rbenv-version

to ignore your locally bundled gems add this to ~/.bundle/config: --- BUNDLE_PATH: vendor/bundle

finally add to your bash profile (probably ~/.bash_profile), so that rbenv is instantiated with your shell eval "$(rbenv init -)"

--restart your shell--

So, how do I use it?

Well, your Rubies are gone, and your gemsets with them. So let's install a Ruby and get a project working again.

$ rbenv install 1.9.3-p0 (specify your favorite flavor if you're not ready for 1.9.3)

$ rbenv rehash to rebuild rbenv's shims, when you install a new system system gem with a binary (like rake).

$ rbenv global 1.9.3-p0 sets a global version of Ruby to be used (instead of your system Ruby).

$ rbenv local 1.9.2-p290 sets the version of Ruby for a specific project directory by creating a .rbenv-version file (which we ignored earlier)

$ gem install bundler to get bundler installed into your current Ruby's gemset.

running bundle in your project directory will now install the gems in your Gemfile directly into your project in vender/bundle.

last, run your project in the context of your bundle: $ bundle exec rails s

Glad it helped, @alexmcpherson
