title: chalice package: Could not install dependencies: graphqlclient==0.2.4
body: <p>While running <code>chalice package</code> command I am getting this error:</p>
  
  <pre><code>$ chalice package --stage preview .chalice/deployments/preview
  Creating deployment package.
  
  Could not install dependencies:
  graphqlclient==0.2.4
  You will have to build these yourself and vendor them in
  the chalice vendor folder.
  
  Your deployment will continue but may not work correctly
  if missing dependencies are not present. For more information:
