我从 GitHub 下载了 OpenCV 文件夹，并按照自述文件的说明为 ios 构建了它。
使用 python opencv/platforms/ios/build_framework.py ios 命令后出现以下错误:
Executing: ['cmake', '-GXcode', '-DAPPLE_FRAMEWORK=ON', '-DCMAKE_INSTALL_PREFIX=install', '-DCMAKE_BUILD_TYPE=Release', '-DIOS_ARCH=armv7', '-DCMAKE_TOOLCHAIN_FILE=/Users/name/Downloads/opencv/platforms/ios/cmake/Toolchains/Toolchain-iPhoneOS_Xcode.cmake', '-DENABLE_NEON=ON', '/Users/name/Downloads/opencv', '-DCMAKE_C_FLAGS=-fembed-bitcode', '-DCMAKE_CXX_FLAGS=-fembed-bitcode'] in /Users/name/Downloads/ios/build/build-armv7-iphoneos

我必须做些什么来修复它？
如果将来有人会遇到同样的问题。 这个问题在master分支，下载分支2.4并在PATH添加CMake构建过程顺利
关于python - 为 iOS 构建 OpenCV 失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42646787/
