我node-gyp configure成功，再执行node-gyp rebuild时 出现这个问题 但是/usr/local/include是有这个文件的，我觉得应该是哪个path没设置正确，但我就是不知道到底要设置什么path

Answer 1

Generally, /usr/include is searched. Otherwise, check whether your /usr/include exists. If it does not exist, try soft linking /usr/local/include to /usr/include.

Answer 2

It’s because you didn’t compile the import path when you installed opencv.

Answer 3

'include_dirs': [
          '/usr/local/include',
        ],

"targets".'link_settings'.'include_dirs' = '/usr/local/include'
I found a way to add this definition to building.gyp, but here comes another 'cstdint' file not found
