ls
cd到項(xiàng)目路徑下
ls
執(zhí)行xcode-select install安裝軟件命令
這個時候報(bào)錯
xcode-select: error: invalid argument 'install'
Usage: xcode-select [options]

-p, --print-pathprint the path of the active developer directory
-s , --switch set the path for the active developer directory
--installopen a dialog for installation of the command line developer tools
-v, --versionprint the xcode-select version
-r, --resetreset to the default command line tools path
