【问题描述】：

早上好，我正在尝试使用 pip install 安装软件包，在本例中是 docker-compose，我想将它安装在 Red Hat 8 中，我已经安装了 docker，但出现以下错误：

[dockermd@srvdevrma1 ~]$ sudo pip3 install docker-compose
WARNING: Running pip install with root privileges is generally not a good idea. Try pip3 install --user instead.
Collecting docker-compose

Could not find a version that satisfies the requirement docker-compose (from versions: )
No matching distribution found for docker-compose

我已经配置了代理和一切：

[dockermd@srvdevrma1 ~]$ env | grep proxy
https_proxy=https://E10697:xxxxxx++@10.162.64.36:8080
http_proxy=http://E10697:xxxxxx++@10.162.64.36:8080

您尝试使用 pip 安装的任何软件包都会发生这种情况

【参考方案1】：

您需要为您sudo 的用户声明代理。 IMO 最简单的解决方案。

sudo -i
export http_proxy=https://E10697:xxxxxx++@10.162.64.36:8080
export https_proxy=https://E10697:xxxxxx++@10.162.64.36:8080
pip3 install docker-compose
exit
