python -m pip install -U pip Errno 11004

Question

我正在尝试更新 pip，但我不断收到以下消息:

H:\>python -m pip install -U pip
Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.con
nection.VerifiedHTTPSConnection object at 0x031AF3B0>: Failed to establish a new connection: [Errno 11004] getaddrinfo failed',)': /simple/pip/

Requirement already up-to-date: pip in c:\users\a256886\appdata\local\programs\python\python36-32\lib\site-packages

我安装了 python 3.6.1，当我运行 pip --version 我看到 pip 9.0.1。

为什么我不能更新？或者使用 pip 安装任何软件包？怎么了？我该如何解决？

你在代理后面。正如您所发现的，您可以将代理传递给 pip使用 --proxy争论:

python -m pip install -U pip --proxy http://username:password@proxy_url:port

或者

pip install --upgrade pip --proxy http://username:password@proxy_url:port

该文档在这里令人困惑，因为它没有提到将协议(protocol)作为代理定义的一部分传递的要求。
