还有docker中pip下载太慢的问题，这里不详细展开

错误原因

docker构建时机器可能无法访问 apt-get 需要连接的服务器来下载软件包列表。这可能是由于网络连接问题、DNS 解析问题或代理设置不正确导致的。

解决方法

在dockerfile中加入更换软件源的操作

• 更换apt的软件源
• 更换pip的软件源

COPY src /root/src
WORKDIR /root/src

• sed -i: 这个命令会直接修改容器中的 /etc/apt/sources.list 文件。

• s/.../.../g: 这是 sed 的替换规则。它会把文件中所有匹配到的 Ubuntu 官方源地址 http://archive.ubuntu.com 和 http://security.ubuntu.com 全局替换成阿里云的镜像源 http://mirrors.aliyun.com。

至于pip怎么换的源，我是直接追加了镜像地址

解决后效果

下载快的飞起，很不错
