title: Can't use pip to install flask
body: <p>I'm trying to install flask but I can't use <code>pip install flask</code> in the windows command line. I'm in the directory C:\Python35, where python is installed. I've tried uninstalling and reinstalling python, and it doesn't seem to be installing pip during the python installation. I'm not sure if i'm not installing Python right. Why can't I use pip?</p>
  
  <p>Here is what i've tried</p>
