I just installed virtualenv and am getting an error trying to create an
environment. Based on some print statements I added, sys.prefix seems to
be getting lowercased somewhere within virtualenv.exe, before runpy.py
starts. And that leads to an error in change_prefix.
I can't figure out what's going on inside virtualenv.exe, so this was as
far as I was able to debug it. Any advice?
C:\Users\Jim>mkvirtualenv lob
mkvirtualenv.bat about to call virtualenv.exe, sys.prefix = C:\Users\Jim\
AppData\Local\Programs\Python\Python36
_run_module_as_main entered, sys.prefix = c:\users\jim\appdata\local\
programs\python\python36
