title: Conda create is stuck at "solving package specifications"
body: <p>I'm trying to create a Python 2.7 virtual environment with Anaconda so I can download some packages that are not compatible with Python 3.4. I'm working in Conda version 4.2.13.</p>
  
  <p>When I type the command <code>conda create -n chemistry python=2.7 anaconda</code> the whole thing freezes at the <code>solving package specifications</code> stage.</p>
  
  <p>Does anyone know what causes this or how I can go about fixing it?</p>
