问题描述：xcode报错

diff: Manifest.lock: No such file or directory

error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.`

解决办法：

关闭当前的工作空间，删除掉文件夹中的workspace，然后重新pod install，install完成之后，通过workspace打开工作空间，clean+build即可，如下所示

rm -rf Runner.xcworkspace

pod install

在pod install之前，请确保已经执行pod setup命令。
