pip 安装依赖链接 [英] pip install dependency links

问题描述

我使用的是 python 版本 2.7 而 pip 版本是 1.5.6.

我想从 url 安装额外的库，就像安装 setup.py 上的 git 存储库一样.

I want to install extra libraries from url like a git repo on setup.py is being installed.

我在 setup.py 的 install_requires 参数中添加了额外的内容.这意味着，我的库需要额外的库并且也必须安装.

I was putting extras in install_requires parameter in setup.py. This means, my library requires extra libraries and they must also be installed.

...
install_requires=[
    "Django",
    ....
],
...

但是像 git repos 这样的 url 在 setup.py 中的 install_requires 中不是有效字符串.假设，我想从 github 安装一个库.我搜索了这个问题，我发现了一些我可以把库放在 dependency_links 中的 setup.py .但这仍然不起作用.这是我的依赖链接定义；

But urls like git repos are not valid string in install_requires in setup.py. Assume that, I want to install a library from github. I have searched about that issue and I found something which I can put libraries such that in dependency_links in setup.py. But that still doesn't work. Here is my dependency links definition;

dependency_links=[
    "https://github.com/.../tarball/master/#egg=1.0.0",
    "https://github.com/.../tarball/master#egg=0.9.3",
], 

链接有效.我可以使用这些网址从互联网浏览器下载它们.这些额外的库仍未随我的设置一起安装.我还尝试了 --process-dependency-links 参数来强制 pip.但结果是一样的.我在 pipping 时不会出错.

The links are valid. I can download them from a internet browser with these urls. These extra libraries are still not installed with my setting up. I also tried --process-dependency-links parameter to force pip. But result is same. I take no error when pipping.

安装后，我在 pip freeze 结果中看到 dependency_links 中没有库.

After installation, I see no library in pip freeze result in dependency_links.

如何让我的 setup.py 安装可以下载它们?

How can I make them to be downloaded with my setup.py installation?

这是我完整的setup.py

from setuptools import setup

try:
    long_description = open('README.md').read()
except IOError:
    long_description = ''

setup(
    name='esef-sso',
    version='1.0.0.0',
    description='',
    url='https://github.com/egemsoft/esef-sso.git',
    keywords=["django", "egemsoft", "sso", "esefsso"],
    install_requires=[
        "Django",
        "webservices",
        "requests",
        "esef-auth==1.0.0.0",
        "django-simple-sso==0.9.3"
    ],
    dependency_links=[
        "https://github.com/egemsoft/esef-auth/tarball/master/#egg=1.0.0.0",
        "https://github.com/egemsoft/django-simple-sso/tarball/master#egg=0.9.3",
    ],

    packages=[
        'esef_sso_client',
        'esef_sso_client.models',
        'esef_sso_server',
        'esef_sso_server.models',
    ],
    include_package_data=True,
    zip_safe=False,
    platforms=['any'],
)

看来，它没有使用dependency_links 中的源代码.

It seems, it does not use the sources in dependency_links.

推荐答案

您需要确保在 install_requires 中也包含依赖项.

You need to make sure you include the dependency in your install_requires too.

这是一个例子 setup.py

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

setup(
    name='foo',
    version='0.0.1',
    install_requires=[
        'balog==0.0.7'
    ],
    dependency_links=[
        'https://github.com/balanced/balog/tarball/master#egg=balog-0.0.7'
    ]
)

这是您的示例 setup.py 的问题:

Here's the issue with your example setup.py:

您在设置的依赖项链接中缺少鸡蛋名称.

You're missing the egg name in the dependency links you setup.

你有

https://github.com/egemsoft/esef-auth/tarball/master/#egg=1.0.0.0

你需要

https://github.com/egemsoft/esef-auth/tarball/master/#egg=esef-auth-1.0.0.0
