Python 3.x 找不到pytest模块

在我的包上运行

pytest

时遇到问题。我有以下结构

我的

conftest.py

有以下内容

"""
Fixtures for test_tcx2gpx
"""
from pathlib import Path
import pytest

from tcx2gpx.tcx2gpx import TCX2GPX

TCX_DIR = Path(__file__).resolve().parents[1]
TCX_FILE = TCX_DIR / 'resources' / '2019-10-20 12:51:21.0.tcx'
GPX_FILE = TCX_DIR / 'resources' / '2019-10-20 12:51:21.0.gpx'


@pytest.fixture
def tcx_file():
    """
    Fixture of TCX file
    """
    return TCX2GPX(TCX_FILE)

在从顶层运行

pytest

时，我被告知

____________________________________________________ ERROR collecting test session ____________________________________________________
/home/neil/.virtualenvs/default/lib/python3.6/site-packages/_pytest/config/__init__.py:458: in _importconftest
    return self._conftestpath2mod[key]
E   KeyError: PosixPath('/mnt/work/python/tcx2gpx/tests/tcx2gpx/conftest.py')

During handling of the above exception, another exception occurred:
/home/neil/.virtualenvs/default/lib/python3.6/site-packages/_pytest/config/__init__.py:464: in _importconftest
    mod = conftestpath.pyimport()

    from tcx2gpx.tcx2gpx import TCX2GPX
E   ModuleNotFoundError: No module named 'tcx2gpx.tcx2gpx'

但是我得到了相同的错误，即使上述目录结构所在的

/mnt/work/python/tcx2gpx

位于

PYTHONPATH

中

我还尝试过使用

python-mpytest

，因为如上所述，这样做应该自动将当前目录包含在

syspath

中。但是我得到了相同的结果，

ModuleNotFoundError

我还发现它描述了安装的

pytest

系统与虚拟环境中的系统之间的冲突，但首先我无法在系统级别卸载它，因为它是我在系统中安装的其他软件包的必需依赖项，其次，我在GitLab CI中运行测试时遇到了相同的错误，我认为没有安装任何其他版本的

pytest

（我必须在测试阶段显式安装它）

如果您真的想知道为什么这样做不起作用，我们将非常感谢您的任何建议或指针。

您不应该在项目顶部有一个

\uuuu init\uuuuuuuuupy.py

文件——这会导致pytest假定父目录是项目的根目录

删除它为我修复了它

---

（免责声明：我是pytest核心开发人员）

它是否显示在

pip列表中

？tcx2gpx.tcx2gpx导入tcx2gpx的导入语句

也不正确。需要更改tcx2gpx导入tcx2gpx

。@wim从看起来不错的文件结构来看，有

tcx2gpx/tcx2gpx.py

（这有点令人困惑，因为OP使用了

tree-f

而不是普通的

tree

）啊，你说得对。我的不好。似乎名称空间的级别太多了。而且测试中的

tcx2gpx

包更让人困惑。谢谢，我删除了顶层

\uuu init\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu目录并运行
python-m“pytest”
解决了这个问题。感谢指针。我仍然不清楚是否需要
\uuuu init\uuuuuuuuuuuy.py
，因为我认为这是python的宿醉，从test文件夹中删除
\uuuuu init\uuuuuuuuuuuuuuuuuuuuuuuuuy.py
会在linting上引入
f010，但我可以努力消除它。
