如何使用'pip'从github链接安装extrarequires`

Question

我将这个python包放在github存储库中。我可以直接从github链接安装它，如下所示：

pip install git+https://github.com/mkdocs/mkdocs.git

---

我也希望这样做，但是安装一些额外的依赖项。仅使用包名时，我们可以执行以下操作：

pip install mkdocs[i18n]

但如果我尝试：

pip install git+https://github.com/mkdocs/mkdocs.git[i18n]

它失败，出现以下错误：

Looking in indexes: https://pypi.org/simple, https://pypi.ngc.nvidia.com

如何使用github链接的额外依赖项？

Answer 1

这项工作：

pip install "git+https://github.com/mkdocs/mkdocs#egg=mkdocs[i18n]"

添加了#egg=mkdocs

Answer 2

下面是来自https://pip.pypa.io/en/stable/cli/pip_install/#examples的示例7：

pip install "mkdocs[i18n] @ git+https://github.com/mkdocs/mkdocs.git"

“@”符号的用法在PEP 440的direct references部分中有详细说明
