title: python egg cache
body: <p>I have 3 projects hosted in amazon bitnami ec2 and my none of project is running. When I check my logs it showing the error as follows:</p>
  
  <blockquote>
    <p>The Python egg cache directory is currently set to: /opt/bitnami/.tmp
    Perhaps your account does not have write access to this directory? You
    can change the cache directory by setting the PYTHON_EGG_CACHE
    environment variable to point to an accessible directory.</p>
  </blockquote>
  
  <p>and my projects are in <code>/opt/bitnami/projects</code> (all 3 project within that directory).</p>
  
  <p>How can I solve this?</p>
