Installing Ruby in Ubuntu 14.04 with Z shell (zsh)2015-09-03
Installing the latest version of Ruby into Ubuntu 14.04 is painless using the method desribed here. If you're using bash that is! If you're using Z shell, which is what all the cool kids are using these days, you need to insert the Ruby environment paths into your Z shell environment instead.
I have edited the commands below from the Go Rails rbenv method.
The first step is to install some dependencies for Ruby.
sudo apt-get update sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Installing with rbenv is a simple two step process. First you install rbenv, and then ruby-build:
cd git clone git://github.com/sstephenson/rbenv.git .rbenv echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc echo 'eval "$(rbenv init -)"' >> ~/.zshrc exec $SHELL git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.zshrc exec $SHELL git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~/.rbenv/plugins/rbenv-gem-rehash rbenv install 2.2.3 rbenv global 2.2.3 ruby -v
Now we tell Rubygems not to install the documentation for each package locally and then install Bundler
echo "gem: --no-ri --no-rdoc" > ~/.gemrc gem install bundler
From this point I followed the GitHub pages tutorial on installing their gem. I find it better to do it via a Gemfile within the working directory for the Jekyll site.
