pytest "Error: could not load path/to/conftest.py"

Question

当我尝试运行 pytest repo/tests/test_file.py 时出现以下错误:

$ pytest repo/tests/test_file.py
Traceback (most recent call last):
  File "/Users/marlo/anaconda3/envs/venv/lib/python3.6/site-packages/_pytest/config.py", line 329, in _getconftestmodules
    return self._path2confmods[path]
KeyError: local('/Users/marlo/repo/tests/test_file.py')

During handling of the above exception, another exception occurred:
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

During handling of the above exception, another exception occurred:

    raise self.ImportMismatchError(modname, modfile, self)

ERROR: could not load /Users/marlo/repo/conftest.py

我的 repo 结构是

lib/
    -tests/
        -test_file.py
app/
    -test_settings.py
pytest.ini
conftest.py
...

其他人已经很好地运行了这段代码，根据 this question (和 this one )，我的结构很好，我没有丢失任何文件。我只能得出结论，我的计算机或项目设置有问题。如果您有任何我可能遗漏的建议或见解，请将它们发送给我!

test_file.py :

def func(x):
    return x + 1

def test_answer():
    assert func(3) == 5

pytest.ini :

[pytest]
DJANGO_SETTINGS_MODULE = app.test_settings
python_files = tests.py test_* *_tests.py *test.py

我有 docker 以及在 docker 之外运行 pytest，对我来说，每当出现这种情况时，影响低得多的修复是删除所有已编译的 python 文件
find . -name \*.pyc -delete
