依赖于setup.py中的git存储库

Question

我试图使一个项目依赖于git依赖项。然而，我似乎无法让它发挥作用。我基本上想要实现的是以下几点，但却行不通：

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


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

我尝试了上面的几个变体，比如添加@master或#egg=wakeonlan-0.2.2，但是这并没有什么区别。

以下操作有效，但仅在使用不推荐使用的pip标志--process-dependency-links时才起作用

#!/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'
    ])

这一产出如下：

$ 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.
Collecting wakeonlan (from spam==0.0.0)
  Cloning https://github.com/remcohaszing/pywakeonlan.git to /tmp/pip-build-mkhpjcjf/wakeonlan
  DEPRECATION: Dependency Links processing has been deprecated and will be removed in a future release.
Installing collected packages: wakeonlan, spam
  Running setup.py install for wakeonlan ... done
  Running setup.py develop for spam
Successfully installed spam wakeonlan-0.2.2

以下是行之有效的办法：

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

同时，在需求文件中添加git url也是有效的。

是否有任何非推荐的方式依赖使用setup.py文件的git url？

Pip >= 9.1 (提交6ec559)将支持PEP508中描述的新的@语法，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中以同样的方式使用，例如：

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

您现在可以尝试使用最新的提交到pip主(用‘错误’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
