从/usr/ opencv4中恢复opencv2 2/文件夹

Question

在安装opencv的过程中，我遇到了很多问题，并且在/usr/include中意外地删除了opencv文件夹。如何以正确的方式恢复它们，以便在尝试catkin_make我的ros工作区时不会发生以下错误？

是否可以将文件夹从/usr/local/include复制到/usr/include，因为我已经成功安装了这些文件夹，还是会导致问题？

您必须简单地使用APT还原/usr/include文件夹内容的功能：

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

/usr/local/include文件夹不受APT控制，因此不能使用上面的命令进行还原。
