Steps to Reproduce

  1. Setup a conda environment and install mayavi (see the Steps to Reproduce in #10984)
  2. Clean up the CRCRLF line-endings (e.g. by following these steps: https://github.com/ContinuumIO/anaconda-issues/issues/10984#issuecomment-499454605)
  3. Start Python and import mayavi:

I suspect this is an issue with the conda build of https://github.com/enthought/mayavi/tree/master/tvtk because a pip install of mayavi (and its apptools and envisage dependencies) works as expected.

Create a conda environment with many mayavi dependencies
