title: Python(Scrapy) unpredictable mistake with "import load_entry_point"
body: <p>I have such problem, I did nothing with Python or Scrapy, but when I started today my computer I got such error. I have found many different posts and tried some tips and advices, unfortunately, they are do not work properly and I worry not to break something else.</p>
  
  <pre><code>Traceback (most recent call last):
    File "/usr/bin/scrapy", line 5, in &lt;module&gt;
      from pkg_resources import load_entry_point
    File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2749, in &lt;module&gt;
      working_set = WorkingSet._build_master()
    File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 444, in _build_master
      ws.require(__requires__)
    File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 725, in require
      needed = self.resolve(parse_requirements(requirements))
    File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 628, in resolve
      raise DistributionNotFound(req)
  pkg_resources.DistributionNotFound: service-identity
  </code></pre>
  
  <p>Therefore, maybe someone had the same error. If yes, please, let me know how you solved it.</p>
  
  <p><strong>UPDATE:</strong>
  I have tried many things and direct search was without real results, only <a href="https://stackoverflow.com/questions/28670554/python-scrapy-issue-with-scrapy-version">Python &amp; Scrapy: Issue with Scrapy version</a> was helpful, I have deleted Scrapy and installed it again. Magic, but it works.</p>
