body: <p>I am trying to use scrape, but I have a problem.</p>
  <blockquote>
  <p>from six.moves import xmlrpc_client as xmlrpclib</p>
  <p>ImportError: cannot import name xmlrpc_client</p>

  <p>Then, I tried <code>pip install --upgrade six scrape</code>, but:</p>
  <pre class="lang-none prettyprint-override"><code>  Found existing installation: six 1.4.1
      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.
  Uninstalling six-1.4.1:
