Docker 容器：导入错误：libGL.so.1：无法打开共享对象文件：没有这样的文件或目录

Question

我有一个使用flask的深度学习项目。我想将其放入 docker 容器中，但是当我启动容器时，它在 web 中显示此错误：

内部服务器错误 服务器遇到内部错误，无法完成您的请求。服务器超载或应用程序出现错误。

这是容器的日志：

请记住，我有一个包含所有包的

requirements.txt

文件。

我尝试重新安装所有软件包，但没有成功。

Answer 1

解决方案是我将此包添加到requirements.txt文件中：

opencv_python_headless

但现在我有一个相机错误：
