通過代理pip安裝包

Question

我嘗試使用代理進行 pip install，代理設置是正確的，因為它適用於 npm install 。 我嘗試的是如下所示，但收到錯誤消息。 任何想法都非常受歡迎！

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

從https://stackoverflow.com/a/33611028/2653663看起來應該是

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

所以端口而不是ip。

Answer 3

set http_proxy=...並set https_proxy=... 。 如果代理有效，應該就足夠了。

請運行以下命令以確保它有效：

curl https://google.com
