title: module 'importlib._bootstrap' has no attribute '_w_long'
body: <p>I am trying to install django-adim-tools using pip, but this is what happens:</p>
  <pre><code>C:\Users\hugo.villalobos&gt;pip install django-admin-tools
  Could not import runpy module
  Traceback (most recent call last):
    File &quot;C:\Python34\Lib\runpy.py&quot;, line 14, in &lt;module&gt;
      import importlib.machinery # importlib first so we can test #15386 via -m
    File &quot;C:\Python34\Lib\importlib\__init__.py&quot;, line 34, in &lt;module&gt;
      _w_long = _bootstrap._w_long
  AttributeError: module 'importlib._bootstrap' has no attribute '_w_long'
  </code></pre>
  <p>I have no idea how to proceed to solve it.</p>
