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,就像正在安装setup.py上的git repo一样。
我在install_requires
的setup.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_requires
的setup.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_links
的setup.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?
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='',

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pip日志;

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-links
的dependency_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。
