Using pytest --pyargs pythonpackagename under a conda environment does not work.
This is a minimal example for reproducing this bug.
Only dummypkg is downloaded from bjodah channel, rest from defaults
$ conda create -c bjodah -n dummy2 python=2.7 dummypkg pytest $ source activate dummy2 $ python -m pytest --pyargs dummypkg ================================================================================================ test session starts ================================================================================================ platform linux2 -- Python 2.7.11, pytest-2.8.5, py-1.4.31, pluggy-0.3.1 rootdir: /home/chempy, inifile: =========================================================================================== no tests ran in 0.00 seconds ============================================================================================ ERROR: file or package not found: dummypkg
the same goes for python3.4. The weird thing is that the package is importable:
$ which python /home/chempy/miniconda2/envs/dummy3/bin/python $ python -c "import dummypkg; print(dummypkg.__file__); from dummypkg.tests.test_core import test_f; test_f(); import pytest; print(pytest.__version__, pytest.__file__); pytest.main(['--pyargs', 'dummypkg'])" /home/chempy/miniconda2/envs/dummy3/lib/python3.4/site-packages/dummypkg-0.1.0-py3.4.egg/dummypkg/__init__.py 2.8.5 /home/chempy/miniconda2/envs/dummy3/lib/python3.4/site-packages/pytest.py ================================================================================================ test session starts ================================================================================================ platform linux -- Python 3.4.4, pytest-2.8.5, py-1.4.31, pluggy-0.3.1 rootdir: /home/chempy, inifile: =========================================================================================== no tests ran in 0.00 seconds ============================================================================================ ERROR: file or package not found: dummypkg
deactivating our environment and using system provided python (Ubuntu 14.04) and pip everything works fine:
$ source deactivate discarding /home/chempy/miniconda2/envs/dummy3/bin from PATH $ export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games $ which python /usr/bin/python $ python -m pip install --upgrade --user pytest git+https://github.com/bjodah/dummypkg.git $ python -m pytest --pyargs dummypkg ================================================================================================ test session starts ================================================================================================ platform linux2 -- Python 2.7.6, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: /home/chempy, inifile: plugins: cov-1.8.0 collected 1 items .local/lib/python2.7/site-packages/dummypkg/tests/test_core.py . ============================================================================================= 1 passed in 0.00 seconds ==============================================================================================
(I've tried with pytest 2.6.2 & 2.8.5 as well and it works)
$ python -c "import dummypkg; print(dummypkg.__file__); from dummypkg.tests.test_core import test_f; test_f(); import pytest; print(pytest.__version__, pytest.__file__); pytest.main(['--pyargs', 'dummypkg'])"
