setup.py忽略完整路径依赖性，而是寻找“最佳匹配".在Pypi中 [英] setup.py ignores full path dependencies, instead looks for "best match" in pypi

问题描述

类似于 https://stackoverflow.com/questions/12518499/pip-ignores-dependency-links-in-setup-py

我正在修改 faker ，因为我希望通过验证器，我希望能够测试我将拥有的新依赖项.

I'm modifying faker in anticipation to an open PR I have open with validators, and I want to be able to test the new dependency i will have.

setup(
    name='Faker',
    ...
    install_requires=[
        "python-dateutil>=2.4",
        "six>=1.10",
        "text-unidecode==1.2",
    ],
    tests_require=[
        "validators@https://github.com/kingbuzzman/validators/archive/0.13.0.tar.gz#egg=validators-0.13.0",  # TODO: this will change  # noqa
        "ukpostcodeparser>=1.1.1",
        ...
    ],
    ...
)

python setup.py test拒绝安装0.13.0版本.

python setup.py test refuses to install the 0.13.0 version.

如果我将故障线移至install_requires=[..](不应存在)

If I move the trouble line up to install_requires=[..] (which SHOULD not be there)

setup(
    name='Faker',
    ...
    install_requires=[
        "python-dateutil>=2.4",
        "six>=1.10",
        "text-unidecode==1.2",
         "validators@https://github.com/kingbuzzman/validators/archive/0.13.0.tar.gz#egg=validators-0.13.0",  # TODO: this will change  # noqa
    ],
    tests_require=[
        "ukpostcodeparser>=1.1.1",
        ...
    ],
    ...
)

• 使用pip install -e .一切都很好-安装正确的版本.
• 使用python setup.py develop相同问题.
• using pip install -e . everything works great -- the correct version gets installed.
• using python setup.py develop same issue.

我的猜测是setuptools/distutils做一些奇怪的事情-pip似乎解决了这个问题.我的问题:该如何解决?

My guess is setuptools/distutils doing something weird -- pip seems to address the issue. My question: how do I fix this?

Easiest way to see the issue at hand:

docker run -it --rm python:3.7 bash -c "git clone https://github.com/kingbuzzman/faker.git; cd faker; pip install -e .; python setup.py test"

更新:由于此问题已得到修复，因此该问题将不再重复出现-所有测试都将通过

推荐答案

不幸的是，setup_requires和tests_require都不支持PEP 508中基于URL的查找或环境标记.您需要使用dependency_links，例如

Unfortunately, neither setup_requires nor tests_require support URL-based lookup or environment markers from PEP 508 yet. You need to use dependency_links, for example

setup(
    ...
    tests_require=["validators>=0.13.0"],
    dependency_links=['git+https://github.com/kingbuzzman/validators@master#egg=validators-0.13.0'],
)
