It’s not required because Python modules live at a fixed location, no? How does pip deal with that? I suppose it needs to modify the search path somehow. > As outlined in my first email in this thread, our use of PYTHONPATH in > wrappers seems to not have the desired effect in the presence of > incompatible packages that are *later* in the PYTHONPATH. > > We also have problems when PYTHONPATH includes modules for both Python 2 > and 3, which happens automatically when these modules are installed into > the same Guix profile.

I agree, though I must say that if PYTHONPATH is not up to the task, I’m not sure what can be done on our side. Thanks, Ludo’.
