Reinstall Ruby Environment for Octopress Using ArchLinux and RVM

When reinstalling- or switching your ArchLinux you’ll need to re-setup you whole Ruby environment, otherwise it’s just NOT going to work. I’m using RVM for this, because I need to install a specific Ruby version (1.9.3) AND I have other projects too.

Install RVM

  • Install Curl:
$ sudo pacman -S curl
$ curl -L | bash -s stable --ruby
  • Now edit .bashrc:
$ nano .bashrc 

Paste this at the end:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
  • Check requirements:
$ rvm requirements
Checking requirements for arch.
Requirements installation successful.
  • Install libyaml:
sudo pacman -S libyaml

Install Ruby

  • Login bash:
$ /bin/bash --login
  • Now install the specific Ruby version of your needings:
$ rvm install ruby-1.9.3-p194
  • Use default Ruby
$ rvm use 1.9.3-p194
  • Install latest gems:
$ rvm rubygems latest

Fetch Octopress and reconfig

  • Now it’s time to fetch your project:
$ git clone ssh://[email protected]/~/git/server.git/ (for example)
  • Gem install bundler:
$ gem install bundler
  • Now intstall the bundler by:
$ bundle install


The whole thing is now ready for use, you’ll just need to enter your emailaddress and name in Git for commiting

  • Enter a name:
$ git config --global "Techswag"
  • Enter an emailaddress:
$ git config --global "webm[email protected]" 

First commit

$ rake generate
$ git add .
$ git commit -am "this is my first commit after reinstalling." 
$ git push


ArchLinux is using Python 3.x and this setup is using 2.x. It might be an issue when rake generate that your log is full of these warnings:

It’s a know issue on ArchLinux (conflict version of Python):
