如何使用 `pip` 从 github link 安装额外要求

Question

我有这个 python 包位于 github 存储库中。我可以像这样直接从 github link 安装它：

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

---

我也想这样做，但要安装一些额外的依赖项。当只使用包名时，我们可以这样做：

pip install mkdocs[i18n]

但如果我尝试：

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

失败并出现以下错误：

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

如何使用 github links 的额外依赖项？

Answer 1

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

Answer 2

这个有效：

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

已添加 #egg=mkdocs。
