python - 如何使用代理进行 pip 安装

Question

我尝试过这个命令

pip install --proxy="username:password@192.168.1.1:3128" packagename

错误消息显示:

顺便说一句，我记得用户名或密码是否有像“.”这样的标点符号。它必须被替换，但我忘记了。谁能提醒我这一点吗？谢谢!

我也被这个问题困扰了。经过对 pip 和 easy_install 代理设置的多次实验后，我放弃并从 here 下载 whl 文件。 。并安装它们:

pip install SomePackage-1.0-py2.py3-none-any.whl
