title: "OSError: [Errno 1] Operation not permitted" when installing Scrapy in OSX 10.11 (El Capitan) (System Integrity Protection)
body: <p>I'm trying to install Scrapy Python framework in OSX 10.11 (El Capitan) via pip. The installation script downloads the required modules and at some point returns the following error:</p>
  
  <pre><code>OSError: [Errno 1] Operation not permitted: '/tmp/pip-nIfswi-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six-1.4.1-py2.7.egg-info'
  </code></pre>
  
  <p>I've tried to deactivate the rootless feature in OSX 10.11 with the command:</p>
  
  <pre><code>sudo nvram boot-args="rootless=0";sudo reboot
  </code></pre>
  
  <p>but I still get the same error when the machine reboots.</p>
  
  <p>Any clue or idea from my fellow StackExchangers?</p>
  
  <p>If it helps, the full script output is the following:</p>
  
  <pre><code>sudo -s pip install scrapy

      DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
