在Docker容器上使用pip安装时出现EnvironmentError: HTTPSConnectionPool。

Question

我刚刚运行了来自https://github.com/puckel/docker-airflow的docker-compose，但由于我需要一个额外的python包，在运行docker exec -it <containerId> bash后尝试手动安装它，但出现以下错误：

之前我可以顺利地运行 pip install pymssql，但现在不知道为什么会出问题了，docker-compose.yml 文件和网络都没有做过任何更改。

我在2020年8月16日遇到了同样的错误。注意到https://files.pythonhosted.org的SSL证书是在8月13日发布的。然后我登录到容器中检查日期，发现日期是8月12日。这就是为什么SSL验证失败的原因。如果你使用的是Windows系统，可以重启Docker桌面来与主机同步时间。但这会导致正在运行的容器停止。如果你不想停止正在运行的容器，那么你需要手动更新Docker容器内部的时间。
