失败的 OpenCV 安装无法卸载

Question

在安装 opencv_contrib 时（在 make -j5 步骤中），我的笔记本电脑进入睡眠状态并在安装时出现错误，并因致命错误而失败。重试 make -j5 再次出现同样的错误。尝试使用 make uninstall 完全卸载 opencv 也完全失败并出现致命错误。

如何从此处全新安装 OpenCV？

运行错误 make uninstall:

Answer 1

您应该尝试 make clean 并再次尝试卸载。此外，您应该从之前的步骤重新开始安装 opencv

Answer 2

您不能直接从 usr/local/...等中删除文件，所以您尝试提供 sudo make uninstall 它会正常工作！
