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，但出现以下错误：

在我能够毫无问题地运行pip install pymssql 之前的几天。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

【解决方案1】：

我在 2020 年 8 月 16 日遇到了同样的错误。注意到https://files.pythonhosted.org SSL 证书是在 8 月 13 日颁发的。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。
