pip安装依赖链接

问题描述 投票:11回答:4

我正在使用python version 2.7pip version is 1.5.6

我想从url安装额外的库,就像正在安装setup.py上的git repo一样。

我在install_requiressetup.py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。

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

但是像git repos这样的网址在install_requiressetup.py中不是有效的字符串。假设,我想从github安装一个库。我已经搜索了这个问题,我发现了一些我可以在dependency_linkssetup.py中放置库的东西。但那仍然行不通。这是我的依赖链接定义;

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。我的设置仍然没有安装这些额外的库。我也试过--process-dependency-links参数强制点。但结果是一样的。我在翻录时没有错误。

安装后,我发现pip freeze中没有库导致dependency_links

如何使用setup.py安装下载它们?

Edited:

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中的来源。

您需要确保在install_requires中包含依赖项。

这是setup.py的一个例子

#!/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'
    ]
)

这是你的示例setup.py的问题:

您在设置的依赖关系链接中缺少鸡蛋名称。

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

Pip一段时间后删除了对dependency_links的支持。 latest version of pip that supports dependency_links is 1.3.1,安装它

pip install pip==1.3.1

您的依赖关系链接应该在那时工作。请注意,dependency_links始终是pip的最后手段,即。如果pypi上存在具有相同名称的包,则会选择超过您的包。

注意,https://github.com/pypa/pip/pull/1955似乎开始允许dependency_links,pip保留它,但你可能需要使用一些命令行开关来使用更新版本的pip。

编辑:从第7点开始......他们重新考虑了dep链接,并且已经启用了他们,即使他们没有删除弃用通知,也不会从他们似乎要留下的讨论中获得。使用pip> = 7,您可以在这里安装

pip install -e . --process-dependency-links --allow-all-external

或者将以下内容添加到pip.conf中,例如: /etc/pip.conf

[install]
process-dependency-links = yes
allow-all-external = yes
trusted-host =
    bitbucket.org
    github.com

编辑

我学到的一个技巧是将版本号提升到非常高的值,以确保pip不喜欢非依赖链接版本(如果这是你想要的东西)。从上面的示例中,使依赖关系链接看起来像:

"https://github.com/egemsoft/django-simple-sso/tarball/master#egg=999.0.0",

还要确保版本看起来像示例或是日期版本,任何其他版本控制将使pip认为它是开发版本并且不会安装它。

启用--process-dependency-linksdependency_links选项是removed in Pip 19.0

相反,您可以使用PEP 508 URL来指定您的依赖关系,即supported since Pip 18.1。以下是setup.py的示例摘录:

install_requires=[
    "numpy",
    "package1 @ git+https://github.com/user1/package1",
    "package2 @ git+https://github.com/user2/package2@branch1",
],

请注意,Pip不支持从PyPI和将来的you will not be able to upload them to PyPI (see news entry for Pip 18.1)安装具有此类依赖性的包。

我遇到了类似的情况,我希望将其作为我的包依赖项之一。然而,Shapely有一个警告,如果你使用Windows,你必须使用http://www.lfd.uci.edu/~gohlke/pythonlibs/的.whl文件。否则,你必须安装一个C编译器,这是我不想要的。我希望用户只需使用pip install mypackage而不是安装一堆其他东西。

如果你有dependency_links的典型设置

setup(
  name = 'streettraffic',
  packages = find_packages(), # this must be the same as the name above
  version = '0.1',
  description = 'A random test lib',
  author = 'Costa Huang',
  author_email = '[email protected]',
  install_requires=['Shapely==1.5.17'],
  dependency_links = ['http://www.lfd.uci.edu/~gohlke/pythonlibs/ru4fxw3r/Shapely-1.5.17-cp36-cp36m-win_amd64.whl']
)

并运行pip install .,它只是在Pypi上选择匀称并在Windows安装上造成麻烦。经过几个小时的研究,我发现这个链接Force setuptools to use dependency_links to install mysqlclient,并基本上使用from setuptools.command.install import install as _install手动安装形状。

from setuptools.command.install import install as _install
from setuptools import setup, find_packages
import pip

class install(_install):
  def run(self):
    _install.do_egg_install(self)

    # just go ahead and do it
    pip.main(['install', 'http://localhost:81/Shapely-1.5.17-cp36-cp36m-win_amd64.whl'])

setup(
  name = 'mypackage',
  packages = find_packages(), # this must be the same as the name above
  version = '0.1',
  description = 'A random test lib',
  author = 'Costa Huang',
  author_email = '[email protected]',
  cmdclass={'install': install}
)

而且脚本运行得很好。希望能帮助到你。
