title: graphlab-create 2.1 installation fails to uninstall 'certifi', a distutils installed project
body: <p>I have installed Anaconda3 on a Windows 8.1 Laptop and wanted to install GraphLab-Create 2.1. When I follow the Installation procedure from Turi, an Anaconda2 is installed as well, which is not what I want.</p>
  
  <p>From within Anaconda3 Navigator 1.8.3 I created a new Environment called "gl-env", by selecting packages Python 2.7. From within Anaconda Navigator I opened a terminal in the gl-env. As described on 
  <a href="https://turi.com/download/install-graphlab-create-command-line.html" rel="noreferrer">https://turi.com/download/install-graphlab-create-command-line.html</a>
  I checked the pip Version: 10.0.1
  Then I entered the pip command as described in Step 5: "Install GraphLab Create". I have a valid product key.</p>
  
  <p>The Installation proceeds until an error message:
  "Cannot uninstall 'certifi'. It is a distutils installed Project and thus we cannot accurately determine which files belog to it which would lead to only a partial uninstall".</p>
  
  <p>I tried to uninstall 'certifi' from the gl-env in Anaconda Navigator, but it gave me 51 packages which would be uninstalled as well. And after doing that, the GraphLab Create Installation process didn't even start.</p>
  
  <p>Any ideas?</p>
