使用 setuptools 从 url 安装 whl

Question

在我的 setup.py 中，我在 required_libraries 参数中指定了许多库。这些通常采用以下形式：oauthlib==2.0.6。现在我还想使用托管在远程 url 上的轮子安装一个库：http://ci.tensorflow.org/view/Nightly/job/nightly-pi-zero/lastSuccessfulBuild/artifact/output-artifacts/tensorflow-1.4.0-cp27-none-any.whl。只需将此作为条目添加到 required_libraries 列表中就会导致错误：

'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Invalid requirement,....

setuptools 上的文档帮助不大。有没有人有进行此类安装的经验？我想这将是一个常见问题，但我可能在谷歌上搜索了错误的单词

Answer 1

使用dependency_links 参数；这在setuptools docs 中有描述。示例：

from setuptools import setup

setup(
    install_requires=['tensorflow'],
    dependency_links=[
        'http://ci.tensorflow.org/view/Nightly/job/nightly-pi-zero/lastSuccessfulBuild/artifact/output-artifacts/tensorflow-1.7.0-cp27-none-any.whl',
    ],
)

运行安装脚本：

$ python setup.py install
running install
running bdist_egg
running egg_info
