title: Django server error: ImportError: No module named dal
body: <p>I'm working with a Django server not coded by me. I have already installed all dependencies using <code>pip install -r requirements</code>, but when I'm trying to execute <code>manage.py</code> I get this error.</p>
  
  <pre><code>Traceback (most recent call last):

  ImportError: No module named dal
  </code></pre>
  
  <p>The solution should be something like <code>pip install dal</code>, but when I try it, I get another error: there is no <code>dal</code> module.</p>
  
  <p>I'm using Python 2.7 and Django 1.9.8</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>My current INSTALLED_APPS</p>
