Tox 失败，因为 setup.py 找不到 requirements.txt

Question

我在我的项目中添加了 tox，我的tox.ini很简单：

[tox]
envlist = py37

[testenv]
deps = 
    -r{toxinidir}/requirements_test.txt
commands = 
    pytest -v

但是当我运行时tox，出现以下错误：

[tox]
envlist = py37

[testenv]
deps = 
    -r{toxinidir}/requirements_test.txt
commands = 
    pytest -v

这是我的setup.py：

ERROR: invocation failed (exit code 1), logfile: /path/to/my_project/.tox/py37/log/py37-2.log

You are using pip version 10.0.1, however version 19.2.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

python setup.py install 工作正常。

似乎 tox 正在 tmp 目录中寻找要求，但在那里找不到。我的配置有问题吗？

我正在使用tox==3.12.1, python==3.7.3, setuptools==41.0.1, 和conda==4.6.9

我已经在 Arch 和 SLES 12 上对此进行了测试，并且两者都得到了相同的结果。

根据@phd 的观点，我发现requirements.txt源代码分发中不存在。添加requirements.txt到已MANIFEST.in解决的问题！
