依赖于 setup.py 中的 git 仓库

Question

我正在尝试使项目依赖于 git 依赖项。但是，我似乎无法让它工作。我基本上想要实现的是以下，但它不起作用：

#!/usr/bin/env python3
from setuptools import setup


setup(
    name='spam',
    version='0.0.0',
    install_requires=[
        'git+https://github.com/remcohaszing/pywakeonlan.git'
    ])

我在上面尝试了几种变体，例如添加@master或#egg=wakeonlan-0.2.2，但这并没有什么不同。

以下方法有效，但仅在使用已弃用的 pip 标志 --process-dependency-links 时有效：

#!/usr/bin/env python3
from setuptools import setup


setup(
    name='spam',
    version='0.0.0',
    install_requires=[
        'wakeonlan'
    ],
    dependency_links=[
        'git+https://github.com/remcohaszing/pywakeonlan.git#egg=wakeonlan-0.2.2'
    ])

这个输出：

$ pip install --no-index -e . --process-dependency-links
Obtaining file:///home/remco/Downloads/spam
  DEPRECATION: Dependency Links processing has been deprecated and will be removed in a future release.

以下确实有效：

pip install 'git+https://github.com/remcohaszing/pywakeonlan.git'

在需求文件中添加 git url 也可以。

是否有任何不推荐使用的方式来使用 setup.py 文件来依赖 git url？

Pip >= 9.1 (commit 6ec559) 将支持新的@ 语法，如PEP508 中所述，其格式为：pkgname@url#sum - 例如：

pip install --no-index packaging@https://files.pythonhosted.org/packages/2f/2b/c681de3e1dbcd469537aefb15186b800209aa1f299d933d23b48d85c9d56/packaging-15.3-py2.py3-none-any.whl#sha256=ce1a869fe039fbf7e217df36c4653d1dbe657778b2d41709593a0003584405f4

这也可以在 setup.py 中以相同的方式使用，例如：

install_requires=['packaging@https://files.pythonhosted.org/packages/2f/2b/c681de3e1dbcd469537aefb15186b800209aa1f299d933d23b48d85c9d56/packaging-15.3-py2.py3-none-any.whl#sha256=ce1a869fe039fbf7e217df36c4653d1dbe657778b2d41709593a0003584405f4']

您现在可以通过对pip master 的最新提交来尝试一下（以“错误”的方式更新 pip！）：

$ pip install https://github.com/pypa/pip/archive/master.zip
$ pip install --no-index packaging@https://files.pythonhosted.org/packages/2f/2b/c681de3e1dbcd469537aefb15186b800209aa1f299d933d23b48d85c9d56/packaging-15.3-py2.py3-none-any.whl#sha256=ce1a869fe039fbf7e217df36c4653d1dbe657778b2d41709593a0003584405f4
