title: Python3 __pycache__ generating even if PYTHONDONTWRITEBYTECODE=1
body: <p>I would like to ask if there is another way to disable creation of <code>__pycache__</code> in the server. </p>
  
  <p>My problem is it keeps generating even if I already set environment variable to <code>PYTHONDONTWRITEBYTECODE=1</code></p>
  
  <p>I want to disable <code>__pycache__</code> because I only keep 5 releases in deployment. This cache is preventing the deletion of the 6th release because the cache is owned by root and can only be deleted through sudo. </p>
  
  <p>I am using capistrano for deployment.</p>
  
  <p>Thank you for your response!</p>
