使用pip安装时，install_requires中列出的程序包将被忽略

Question

可能是在某个地方被问到并得到了答案，但我搜索了很多，但没有找到哪里。抱歉重复。

我有一个项目(https://github.com/PyFPGA/openflow)这取决于pyyaml:

setup(
...,
install_requires=['pyyaml']
)

与pip3 install -e .一起安装时，不会安装pyyaml。可通过以下方式进行验证：

$ virtualenv venv1 --python=python3
$ venv1/bin/python3 -m pip install -e .

它在我的计算机中失败(我知道，python3.5已被弃用(，但在GitHub操作中也会失败(https://github.com/PyFPGA/openflow/pull/7/checks?check_run_id=2171303843)使用ubuntu-latest(使用Python 3.6、3.7、3.8和3.9(

我不想有变通办法。我知道install_requires是指定强制依赖项的方法。我错了？

提前感谢Rodrigo

我解决了我的问题。它与install_requires无关。为了阅读我的项目版本，我导入了导入yaml的文件(尚未安装(。因此，我避免在setup.py.中导入我的库
