New issue 742: Difference of sys.path between running py.test and testdir.runpytest https://bitbucket.org/pytest-dev/pytest/issue/742/difference-of-syspath-between-running
Daniel Hahler: I've noticed that pytest's runpytest method fails when pies2overrides is installed in the virtualenv, which adds a reprlib.py file into site-packages. While this is clearly an [issue with pies](https://github.com/timothycrosley/pies/issues/44), pytest is triggering it by calling its script from this site-packages dir. % virtualenv venv % venv/bin/pip install pytest pies2overrides==2.6.5 # Simulate `testdir.runpytest`: % venv/bin/python venv/lib/python3.4/site-packages/pytest.py Maybe pytest could use another approach here to call itself? And/or something like `sys.path.pop(0)` in the script? I might be missing something here, of course, but it seems like the behaviour/setup of the Python path differs between running `py.test` and `runpytest`, which should be avoided.
