Installing Vim with Ruby support

OSX (Mavericks)

Mavericks already ships with Ruby-enabled Vim. 😃

If you wish to install a newer version (recommended), check out RVM and Homebrew.

# Assuming that you already installed RVM and Homebrew
rvm install ruby
rvm use ruby
brew install vim

Ubuntu

sudo apt-get install vim-nox

Arch Linux

sudo pacman -S gvim

Centos

You can build the recent version of Vim from source.

• Installing Vim on CentOS 6.3

Windows

Parallel installer of vim-plug may not work smoothly on Windows, but you can still try it.

Check out the relevant section from of my article, Installing Vim with Ruby support. It's a little outdated, but you'll get the idea.
