title: How to install and run compass with rvm and gem?
body: <p>OS: Mint Linux 11 64bit</p>
  
  <p>I know nothing about ruby, I just want Compass.</p>
  
  <p>I've installed rvm and ruby 1.9.3, and set the default ruby</p>
  
  <pre><code>$ rvm list
  
  rvm rubies
  
  =* ruby-1.9.3-p125 [ x86_64 ]
  
  # =&gt; - current
  # =* - current &amp;&amp; default
  #  * - default
  </code></pre>
  
  <p>I've installed compass via gem</p>
  
  <pre><code>$ gem list
  
  *** LOCAL GEMS ***
  
  bundler (1.1.3)
  chunky_png (1.2.5)
  compass (0.12.1)
  fssm (0.2.8.1)
  rake (0.9.2)
  rubygems-bundler (0.2.8)
  sass (3.1.15)
  </code></pre>
  
  <p>But I cannot run <strong>compass</strong>, because gem/bin is not in $PATH</p>
  
  <p>I added it to $PATH and run compass again:</p>
  
  <pre><code>$ compass
  /home/il/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find compass (&gt;= 0) amongst [bigdecimal-1.1.0, io-console-0.3, json-1.5.4, minitest-2.5.1, rake-0.9.2.2, rdoc-3.9.4] (Gem::LoadError)

  </code></pre>
