如何让 pip 在代理服务器后面工作 [英] How to get pip to work behind a proxy server

问题描述

我正在尝试使用 python 包管理器 pip 来安装一个包，它是来自 Internet 的依赖项.但是，我在我大学的代理后面，并且已经设置了 http_proxy 环境变量.但是当我尝试安装这样的包时:

I am trying to use python package manager pip to install a package and it's dependencies from the internet. However I am behind a proxy in my college and have already set the http_proxy environment variable. But when I try to install a package like this:

pip install TwitterApi

我在日志文件中收到此错误:

I get this error in the log file:

Getting page http://pypi.python.org/simple/TwitterApi
Could not fetch URL http://pypi.python.org/simple/TwitterApi: <urlopen error [Errno 111] Connection refused>
Will skip URL http://pypi.python.org/simple/TwitterApi when looking for download links for TwitterApi
Getting page http://pypi.python.org/simple/
Could not fetch URL http://pypi.python.org/simple/: <urlopen error [Errno 111] Connection refused>

我什至尝试像这样显式设置我的代理变量:

I even tried setting my proxy variable explicitly like this:

pip install --proxy http://user:password@proxyserver:port TwitterApi

但我仍然遇到同样的错误.如何让 pip 在代理服务器后面工作.

But I still get the same error. How do I get pip to work behind a proxy server.

推荐答案

pip的proxy参数，根据pip --help，格式为scheme://[user:passwd@]proxy.server:port

The pip's proxy parameter is, according to pip --help, in the form scheme://[user:passwd@]proxy.server:port

您应该使用以下内容:

pip install --proxy http://user:password@proxyserver:port TwitterApi

此外，应该遵守 HTTP_PROXY 环境变量.

Also, the HTTP_PROXY env var should be respected.

请注意，在早期版本中(无法追踪代码中的更改，抱歉，但文档已更新此处)，您必须将 scheme:// 部分保留下来才能使其工作，即 pip install --proxy user:password@代理服务器:端口

Note that in earlier versions (couldn't track down the change in the code, sorry, but the doc was updated here), you had to leave the scheme:// part out for it to work, i.e. pip install --proxy user:password@proxyserver:port
