点安装依赖项链接 [英] pip install dependency links

问题描述

我正在使用python version 2.7和pip version is 1.5.6.

我想从URL安装额外的库，例如正在安装setup.py上的git repo.

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参数中添加了额外内容.这意味着，我的库需要额外的库，并且还必须安装它们.

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git repos之类的网址在setup.py的install_requires中不是有效的字符串.假设，我想从github安装一个库.我已经搜索了该问题，发现了一些可以放置库的内容，例如setup.py中的dependency_links.但这仍然行不通.这是我的依赖项链接定义；

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Internet浏览器下载它们.在我的设置中，这些额外的库仍未安装.我还尝试了--process-dependency-links参数来强制点子.但是结果是一样的.抽纸时我不会出错.

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，在dependency_links中看不到pip freeze中的任何库.

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

如何使它们随我的setup.py安装一起下载?

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'],
)

这是点子记录；

似乎，它没有使用dependency_links中的源.

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

推荐答案

您还需要确保在您的install_requires中也包括依赖项.

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

这是一个示例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:

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

您需要

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