从 /usr/include 恢复 opencv2/opencv4 文件夹

我在安装 opencv 时遇到了很多问题，在此过程中我不小心删除了/usr/include。我怎样才能以正确的方式恢复它们，以便当我尝试 catkin_make 我的 ros 工作区时不会发生以下错误？

由于我保留了成功安装后剩下的文件夹，是否可以将文件夹从 /usr/local/include 复制到 /usr/include ？这是否会导致问题？

答案1

您只需使用 APT 的功能即可恢复/usr/include文件夹内容：

sudo apt-get install --reinstall \
$(dpkg -S /usr/include/ | sed "s/,//g" | sed "s|: /usr/include||")

该/usr/local/include文件夹不受 APT 控制，因此无法使用上述命令恢复。
