OpenCV安装失败，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，在安装过程中出现错误，导致致命错误。重试make -j5又出现了同样的错误。使用make uninstall完全卸载opencv的尝试也完全失败，从而导致致命错误。

如何从这里重新安装OpenCV？

运行make uninstall时出错

Answer 1

您应该尝试make clean并尝试重新卸载。此外，您还应该从前面的opencv安装步骤重新启动。

Answer 2

您不能直接从usr/local/.等删除文件，所以您尝试给sudo、make、--它会正常工作！
