I was given the advice by Apurva Badithela to install TuLiP by using these commands
$ git clone https://github.com/tulip-control/tulip-control.git
$ cd tulip-control
$ git checkout eeci2020
$ pip install wheel
$ pip install cvxopt
$ pip install -r requirements.txt
$ python setup.py install
(These directions were found towards the bottom of https://murray.cds.caltech.edu/EECI-IGSC_2020.)

I used a virtual environment (venv) when doing these commands. Everything worked well, except when running python setup.py install, I got the message
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Failed to build PLY table. Please run setup.py again.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This issue was brought up in #132 (comment), where the advice was to disable pip's caching behavior with --no-cache-dir. I have tried adding this flag to the pip install's (pip install wheel, pip install cvxopt, pip install -r requirements.txt), but I still run into the same issue.

Does anyone know how to resolve this issue? Thank you!
