title: Exporting a conda environment with local pip installs
body: <p>I have exported my currently active environment with </p>
  
  <pre><code>conda env export &gt; environment.yml
  </code></pre>
  
  <p>This is very convenient since it keeps track of both conda and pip installed packages. However, I have a few packages (shapely and basemap for example) installed locally by pip from a .whl file from Christoph Gohlke's compiled packages for Windows. When I try to recreate my environment by </p>
  
  <pre><code>conda env create -f environment.yml
  </code></pre>
  
  <p>pip returns with an error since it cannot find these packages in its index (obviously). Is there a way to tell pip in the conda export step where to look for these local packages? The .whl files can be assumed to be in the same directory as the environment.yml file.</p>
