我正在尝试libopencv-dev通过进行安装apt-get install。所以我运行了
sudo apt-get install libopencv-dev
并且它似乎安装了该软件包。但是，当我检查 lib 文件所在的目录时，我没有看到它们。
根据 dpkg，此目录是/usr/lib/x86_64-linux-gnu。但是 lib 文件既不在这里，也不在我的计算机上的其他地方。
我该如何解决这个问题？我已经尝试卸载并重新安装 libopencv-dev，但没有效果。

我用来pkg-config --cflags --libs将 c++ 程序链接到 opencv 库。运行的输出 pkg-config --cflags --libs opencv是：

答案1
当你删除libopencv-dev一些没有被删除的 opencv lib 时，运行：
sudo apt list --installed | grep opencv
您可以检查某些库是否仍然存在并将其删除。然后您可以尝试重新安装 libopencv。
这有帮助。
