PsychoPy 1.90 install on Ubuntu 18.04

[drkitty]

First failed using pip install because of wxpython.  Installed the set of requirements that were missing and passed the wheel phase.  But, now it seems to be fine and then suddenly ends with a segmentation fault.  No idea why.  Any suggestions? Neurodebian is still at 1.85 version.  Here's the last part of the attempted "pip install psychopy" command:

Using verbose mode in pip I get:

 Compiling /tmp/pip-build-_pWskG/gevent/gevent/_socket3.py ...

Not sure what this is or what to do about it.
