个人估计是访问GITHUB出错引起的。墙内无法访问，于是 参照https://blog.csdn.net/qq_30155503/article/details/79643403下载https://download.csdn.net/download/qq_30155503/10305922用FTP传到pi中解压

找资料顺便学了一条新指令，用4个核去编译带 -j4就可以了，不然编译很慢。
sudo make -j4
这时候卡住了,其实还是在运行的，睡一觉起来看见已经完成了
sudo make install
sudo ldconfig
测试

说明安装成功了。
总结一下，由于github被封，所有opencv文件都要自己从CSDN下载，解压。编译出现的问题都是缺少文件或者路径不对，通过自行下载或者复制对应文件到对应路径解决。
