Steve Dower added the comment: Seems like a fairly obvious bug. From https://docs.python.org/3/c-api/init.html#c.Py_SetPath
> This also causes ... sys.prefix and sys.exec_prefix to be empty. > It is up to the caller to modify these if required after calling > Py_Initialize(). Apparently you can't set `sys.[exec_]prefix` before calling Py_Initialize, and you can't call Py_Initialize without setting `sys.[exec_]prefix` (much like #20891, where you can't initialize threads without holding the GIL, and you can't acquire the GIL without having initialized threads.) I don't know how to go about resolving this though (my changes were limited to getpathp.c - and I really need to go add the same changes to the non-Windows getpath.c too...). The best way seems to be forcing Nick to finish PEP 432, but unfortunately I have no leverage over him :) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11320> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
