title: No module named pyvirtualdisplay
body: <p>I have this import in python code</p>
  
  <pre><code>import time
  import sys
  from pyvirtualdisplay import Display
  from selenium import webdriver
  </code></pre>
  
  <p>when I run it from centos consol it runs correctly without any error.</p>
  
  <p>Then I created a php file to run the python script with exec php function, and when I run it from centos consol, it runs correctly too, but when I run it from the browser it gives me this error</p>
  
  <blockquote>
    <p>from pyvirtualdisplay import Display
    ImportError: No module named pyvirtualdisplay</p>
  </blockquote>
  
  <p>I tried to give apache the right of executing the python file, but still the same problem.</p>
  
  <p>Any idea about how to fix it?</p>
