Carthage管理工具的使用

安装/更新Homebrew工具

• 1、/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
• 2、brew install carthage
  如果抱警告：Warning: carthage 0.30.1 is already installed, it’s just not linked You can use brew link carthage to link this version.
• 3、brew link carthage
• 4、brew install carthage
  如果还是报警告：Warning: carthage 0.30.1 is already installed and up-to-date To reinstall 0.30.1, run brew reinstall carthage
• 5、brew reinstall carthage 成功了

第二步：源码方式=>项目安装carthage

• 1、在项目根目录新建carthage文件
  命令：touch Cartfile
• 2、打开Cartfile文件添加第三方库
  例如：github “rs/SDWebImage”
• 3、安装命令：carthage update
  可能会静态库编译不过报错，错误信息如下：

*** Fetching SDWebImage
*** Checking out SDWebImage at “4.4.2”
*** xcodebuild output can be found in /var/folders/7w/4gr2dxc57v3656mjgqmv9mkm0000gn/T/carthage-xcodebuild.XWTgwJ.log
A shell task (/usr/bin/xcrun xcodebuild -workspace /Users/yangshaohong/Desktop/Course/iOS/framework/project/Dream_20180902_TZVideo_02/Carthage/Checkouts/SDWebImage/SDWebImage.xcworkspace CODE_SIGNING_REQUIRED=NO CODE_SIGN_IDENTITY= CARTHAGE=YES -list) failed with exit code 72:
xcrun: error: unable to find utility “xcodebuild”, not a developer tool or in PATH

解决办法：为Carthage是先将第三方框架编译成动态库(.framework的二进制文件)，所以需要先指定一个编译工具。在Xcode > Preferences > Locations中的下拉菜单里选择命令行工具。
