python - 环境错误 : HTTPSConnectionPool while pip install on docker container

Question

我只是从 https://github.com/puckel/docker-airflow 运行 docker-compose但由于我需要一个额外的 python 包，我尝试在运行 docker exec -it <containerId> bash 后手动安装它但我有以下错误:

在我能够运行 pip install pymssql 之前的几天没有问题。不知道为什么现在会发生这种情况，没有对 docker-compose.yml 文件进行任何更改，也没有在网上进行更改

我在 2020 年 8 月 16 日遇到了同样的错误。注意到 https://files.pythonhosted.org SSL证书于8月13日颁发。然后我登录到容器并检查日期，日期是 8 月 12 日。这就是 SSL 验证失败的原因。如果您在 Windows 上，请重新启动 docker 桌面以与主机同步时间。但这会杀死你正在运行的容器。如果您不想杀死正在运行的容器，则必须手动更新 docker 容器内的时间。
