运行carthage update到一半，报错：

Build Failed Task failed with exit code 65: /usr/bin/xcrun xcodebuild -workspace /Users/maor/myProj/myProj/Carthage/Checkouts/Alamofire/Alamofire.xcworkspace -scheme Alamofire\ watchOS -configuration Release -derivedDataPath /Users/maor/Library/Caches/org.carthage.CarthageKit/DerivedData/Alamofire/3.5.1 -sdk watchos ONLY_ACTIVE_ARCH=NO BITCODE_GENERATION_MODE=bitcode CODE_SIGNING_REQUIRED=NO CODE_SIGN_IDENTITY= CARTHAGE=YES clean build

This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details: /var/folders/6s/5fm277hs03qb526nqykyplk40000gn/T/carthage-xcodebuild.JxFgDC.log 解决方案》 carthage update --platform ios 或者 carthage update --platform ios --no-use-binaries

安装：brew install Carthage

查看版本：Carthage version 创建一个空的Carthage文件：touch Cartfile 保存并关闭cartfile文件，使用cartfile安装框架：Carthage update --platform iOS
