title: Widget tweaks error ModuleNotFoundError: No module named 'widget_tweaks' with Django forms
body: <p>I am trying to customize my Django forms using widget tweaks for an app I'm building with a group and I keep getting an error: </p>
  
  <p><code>ModuleNotFoundError: No module named 'widget_tweaks'</code></p>
  
  <p>I don't understand why. </p>
  
  <p>I installed the module on my mac with <code>$ pip install django-widget-tweaks</code> and placed <code>'widget_tweaks'</code> in the <code>INSTALLED_APPS = [...]</code> part of my app's <code>settings.py</code> file. Those were the only 2 things I saw that I needed to do after reading the documentation for how to use widget tweaks.</p>
  
  <p><code>settings.py</code> file snippet:</p>
  
  <pre><code>INSTALLED_APPS = [
      'django.contrib.admin',
      'django.contrib.auth',
      'django.contrib.contenttypes',
      'django.contrib.sessions',
      'django.contrib.messages',
      'django.contrib.staticfiles',
      'PupsToPet.apps.PupstopetConfig',
      'widget_tweaks',
     #'django.contrib.easy_maps',
  ]
  </code></pre>
