docker - Windows 上的 Docker 构建未能建立新连接 Errno 11001 getaddrinfo failed

Question

到达此步骤时，Docker 构建失败：

运行 pip install -r requirements.txt

其他一些答案建议添加 --dns 或使用代理服务器设置，但它们都不起作用（--dns 是一个未知标志）。

所有 Docker Build 命令都会发生这种情况。我已经尝试过我的家庭网络，因为我认为我的工作网络导致了这个错误。但同样的错误结果。这个相同的构建命令在 2 周前起作用。

Could not find a version that satisfies the requirement Flask (from -r requirements.txt (line 1)) (from versions: )

找不到 Flask 的匹配分布（来自 -r requirements.txt（第 1 行））命令 'powershell -Command $ErrorActionPreference = 'Stop'; $ProgressPreference = '静默继续'; pip install -r requirements.txt' 返回一个非零代码：1
