Storing debug log for failure in /home/dmacs/.pip/pip.log
我甚至尝试将代理设置为:

sudo pip --proxy http://user:pass@localhost:port install scikit-learn
有人能帮我解决这个问题吗

提前感谢

根据详细信息:

a。您正在安装的服务器存在网络问题,代理命令似乎无法解决该问题。基本上,它无法从pip下载列表

b。如果网络正在运行,请尝试以下操作:

sudo pip install -U pip
sudo pip install -U scikit-learn

您使用的是什么版本的pip?以防万一:
pip--version
