取决于setup.py中的git存储库

Question

I'm trying to make a project depend on a git dependency. However, I can't seem to get it to work. What I basically want to achieve is the following, but it doesn't work:

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


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

I tried several variations on the above, such as adding @master or #egg=wakeonlan-0.2.2 , but this doesn't make a difference.

The following works, but only when using the deprecated pip flag, --process-dependency-links :

#!/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'
    ])

This outputs:

$ 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)

Installing collected packages: wakeonlan, spam
  Running setup.py install for wakeonlan ... done

The following does work:

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

Also adding the git url in a requirements file just works.

Is there any non deprecated way to depend on a git url using a setup.py file?

Pip >= 9.1 (commit 6ec559) will have support for the new @ syntax as described in PEP508 , which takes the format: pkgname@url#sum - eg:

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

This will also be useable in setup.py in the same way, eg:

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

You can try this out just now with the latest commit to pip master (updating pip the 'wrong' way!):

$ pip install https://github.com/pypa/pip/archive/master.zip
