使用 pip 安装时会忽略 install_requires 中列出的软件包

如何解决使用 pip 安装时会忽略 install_requires 中列出的软件包

可能有人在某处询问并回答过，但我搜索了很多，但没有找到在哪里。如有重复，请见谅。

我有一个依赖于 pyyaml 的项目 (https://github.com/PyFPGA/openflow)：

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

与 pip3 install -e . 一起安装时，未安装 pyyaml。可以通过以下方式验证：

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

它在我的计算机上失败（我知道，python3.5 已弃用），但在使用 ubuntu-latest（使用 Python 3.6、3.7、3.8 和 3.9）的 GitHub 操作 (https://github.com/PyFPGA/openflow/pull/7/checks?check_run_id=2171303843) 中也失败。

我不想要解决方法。我了解 install_requires 是指定强制依赖项的方法。我错了吗？

解决方法

我解决了我的问题。它与 install_requires 无关。为了读取我的项目的版本，我导入了导入 yaml（尚未安装）的文件。因此，我避免在 setup.py 中导入我的库。
