导入错误：CentOS 上的 libGL.so.1

Question

当我尝试import cv2在 python 中时，我收到以下错误：

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

我发现这个线程，其建议我安装libgl1-mesa-glx，但我不知道如果这是仅适用于Ubuntu的，因为我在CentOS，当我尝试sudo yum install libgl1-mesa-glx，我得到No package libgl1-mesa-glx available.另外，当我添加了安装到我的dockerfile我得到这个错误：The command '/bin/sh -c yum install libgl1-mesa-glx' returned a non-zero code: 1

然后我找到了一个看起来像Fedora 的解决方案来解决同样的问题，说使用mesa-libGL-devel. 当我sudo yum install mesa-libGL-devel看起来安装正确时，但是当我将它添加到我的 dockerfile 时，我得到了The command '/bin/sh -c yum install mesa-libGL-devel' returned a non-zero code: 1.

我还应该尝试什么？

编辑：这是Dockerfile：

只需添加此命令：

yum install mesa-libGL
