title: Installing Compass & Susy on Ubuntu 12.04
body: <p>I'm trying to install Compass and Susy on my Ubuntu 12.04.</p>
  
  <p>What I have tried are the following steps on the console:</p>
  
  <pre><code>sudo apt-get install rubygems1.8
  sudo gem install rubygems-update # Instead of sudo gem update --system
  sudo update_rubygems
  sudo gem install compass # Installing Compass &amp; Sass
  sudo gem install susy
  </code></pre>
  
  <p>So the gems are installed and will be listed when I do the following command:</p>
  
  <pre><code>gem list
  </code></pre>
  
  <p>But now, when I try to create a new compass project with</p>
  
  <pre><code>compass create project
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>/usr/local/bin/compass: /usr/bin/ruby1.9.1: bad interpreter: No such file or directory
  </code></pre>
  
  <p>My current ruby version is 1.8.7. So I installed ruby 1.9.1 and get it working.
  The console still says the current ruby version is 1.8.7</p>
  
  <p>My question: Do I have to run with both ruby versions to get that working? Is there another way under ubuntu? It's working, I know, but it's a bit confusing.</p>
