环境：MacOS 10.12，CMake 3.9.0，python 2.7
我尝试使用此tutorial在Mac上编译Opencv，在我按照步骤8后，我得到如下错误：
/Users/niceycb/opencv/modules/videoio/src/cap_qtkit.mm:46:9: fatal error:
'QTKit/QTKit.h' file not found
#import <QTKit/QTKit.h>

我试图解决＆＃39; QTKit / QTKit.h＆＃39;找不到文件＆＃39;，我跟着this。
一个解决方案是：
brew reinstall opencv3 --HEAD --with-python2 --with-ffmpeg --with-tbb --with-contrib
错误是
Error: opencv3: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-science/opencv3.rb:1: syntax error, unexpected '!', expecting end-of-input
?SDγ?qm?????5??...)?
^
另一个解决方案是使用$ brew编辑opencv3并注释以下4行：
if build.with?("python3") && build.with?("python")
# Opencv3 Does not support building both Python 2 and 3 versions
odie "opencv3: Does not support building both Python 2 and 3 wrappers"
end
然后我使用$ brew install opencv3 --with-contrib。但是发生了同样的错误。
Error: opencv3: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-science/opencv3.rb:1: syntax error, unexpected '!', expecting end-of-input
?SDγ?qm?????5??...)?
