   > My proposed solution would be to prepend `PIP_USER=false` to the construction of the call to pip within `utils/python_virtualenv.py` here:
   
   I don’t think that’s right, that command is used to invoke `virtualenv`, not `pip`. And prepending won’t work because that is a Bash-specific syntax and does not work with `subproces.Popen()` (unless `shell=True` but please don’t do that).
   
   One possible fix would be to introduce an `environ` argument to `execute_in_subprocess()` so the `PIP_USER` environment variable can be removed when invoking pip.
