我正在尝试在CircleCI上运行pytest，本地我没有问题，但是当我执行shell命令时
PYTHONPATH=. pytest --cov-report html:$CIRCLE_ARTIFACTS/htmlcov --nomigrations
我得到以下追溯：

ImportError: No module named test
pytest-django found a Django project in /home/ubuntu/rit-das-pdp (it contains manage.py) and added it to the Python path.
If this is wrong, add "django_find_project = false" to pytest.ini and explicitly manage your Python path.
PYTHONPATH=. pytest --cov-report html:$CIRCLE_ARTIFACTS/htmlcov --nomigrations returned exit code 1
我不知道错误说的是什么或如何调试它。
