How to get pip to work behind a proxy server
提问by Annihilator8080
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_proxyenvironment variable. But when I try to install a package like this:
我正在尝试使用 python 包管理器 pip 来安装一个包，它是来自互联网的依赖项。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软件包时：
pip install TwitterApi
I get this error in the log file:
我在日志文件中收到此错误：
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>
I even tried setting my proxy variable explicitly like this:
我什至尝试像这样显式设置我的代理变量：
pip install --proxy http://user:password@proxyserver:port TwitterApi
But I still get the same error. How do I get pip to work behind a proxy server.

The pip's proxy parameter is, according to pip --help, in the form scheme://[user:passwd@]proxy.server:port
pip 的代理参数是，根据pip --help，在形式scheme://[user:passwd@]proxy.server:port
You should use the following:
您应该使用以下内容：
pip install --proxy http://user:password@proxyserver:port TwitterApi
Also, the HTTP_PROXYenv var should be respected.
此外，HTTP_PROXY应该尊重 env var。
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
请注意，在早期版本中（无法追踪代码中的更改，抱歉，但文档已在此处更新），您必须将scheme://部分保留下来才能使其正常工作，即pip install --proxy user:password@proxyserver:port

At least for pip 1.3.1, it honors the http_proxy and https_proxy environment variables. Make sure you define both, as it will access the PYPI index using https.
至少对于 pip 1.3.1，它支持 http_proxy 和 https_proxy 环境变量。确保您定义了两者，因为它将使用 https 访问 PYPI 索引。
export https_proxy="http://<proxy.server>:<port>"
pip install TwitterApi

Old thread, I know, but for future reference, the --proxy option is now passed with an "="
我知道旧线程，但为了将来参考， --proxy 选项现在通过“=”传递
Example:
例子：
$ sudo pip install --proxy=http://yourproxy:yourport package_name
回答by Ruben
at least pip3 also works without "=", however, instead of "http" you might need "https"
至少 pip3 也可以在没有“=”的情况下工作，但是，您可能需要“https”而不是“http”
Final command, which worked for me:
最终命令，对我有用：
sudo pip3 install --proxy https://{proxy}:{port} {BINARY}

First Try to set proxy using the following command

Then Try using the command
然后尝试使用命令
pip install ModuleName
回答by Gary Mendonca
On Ubuntu, you can set proxy by using
在 Ubuntu 上，您可以使用设置代理
export http_proxy=http://username:password@proxy:port
export https_proxy=http://username:password@proxy:port
or if you are having SOCKS error use
或者如果您遇到 SOCKS 错误，请使用
export all_proxy=http://username:password@proxy:port
Then run pip
然后运行pip
sudo -E pip3 install {packageName}
