通过代理pip安装包

Question

我尝试使用代理进行 pip install，代理设置是正确的，因为它适用于 npm install 。 我尝试的是如下所示，但收到错误消息。 任何想法都非常受欢迎！

set http_proxy=http://<username>:<password>@<proxy_server>:<port>

set https_proxy=https://<username>:<password>@<proxy_server>:<port>

pip install Flask

Collecting Flask

Answer 1

pip install packageName --proxy proxy_Server:portnumber

ex: pip install numpy --proxy https://myproxy@myserver.com:9090

Answer 2

从https://stackoverflow.com/a/33611028/2653663看起来应该是

set https_proxy=<domain><username>:<password>@<proxy_server>:<port>

所以端口而不是ip。

Answer 3

set http_proxy=...并set https_proxy=... 。 如果代理有效，应该就足够了。

请运行以下命令以确保它有效：

curl https://google.com
