rbenv.md

Set up rbenv

Install rbenv:

$ git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc
$ . ~/.bashrc

Check if rbenv was set up:

$ type rbenv
# => "rbenv is a function"

Then install rbenv-build to manage Ruby versions:

$ git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

Usage

$ rbenv install 2.1.2
$ rbenv global 2.1.2

When you update my-application-template.rb don't forget to update the link in ~/.railsrc as well.

My previous .railsrc

--template=https://gist.githubusercontent.com/dwayne/6e44bda8a9f28d9353ee/raw/7250f3a3d09cbd05c767c4bd54037de177c94d7f/my-application-template.rb

Fast, consistent setup for your Ruby and Rails tools
