【FAQ】xcodebuild in command line，报错：No architectures to compile for xxx，怎么办？

如题，xcodebuild命令行执行时，报错：

$xcodebuild -project 'test.xcodeproj' -configuration 'Debug' -sdk 'iphonesimulator' clean build 

错误：No architectures to compile for (ARCHS=i386, VALID_ARCHS=arm64 armv7 armv7s)

后来发现，其实加上几个参数就好了：-arch "i386" ONLY_ACTIVE_ARCH=YES VALID_ARCHS="i386 x86_64"

$xcodebuild -project 'test.xcodeproj' -configuration 'Debug' -sdk 'iphonesimulator' \
	clean build -arch "i386" ONLY_ACTIVE_ARCH=YES VALID_ARCHS="i386 x86_64"

具体每个参数啥意思，请自行百度：）
