    @mayli 我是终端用户,我看最后有 443 、https 、timeout ,基本就是国内网络问题,无科学方法的情况反复尝试几下也会成功。但那一堆错误真的吓人。

    @iorilu 我没手动设置任何源最后也会成功,很明显是网络问题,问题是 python 直接优雅地说出最后一句就行,不用抛出中间那满屏的一坨坨。根本看了也是白看。反正我是不会看的,只看最后!

    虽然,最终,都会成功。但成功之前那一坨坨,真的没办法去掉吗?不是说 python 是优雅的吗?

    其实,科学一下,就不会一坨坨的啦,但科学不是每时每刻都有啊。

    @youngce 一坨错误,非绿则红,不是速度慢,就是说 SSL 时间超时。与命令本身是否有误无关。
