解决cocoapods diff: /../Podfile.lock: No such file or directory

 diff: /../Podfile.lock: No such file or directory   

  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.

解决方法：

在工程设置中的 Build Phases 下修改 Check Pods Manifest.lock 的路径

${PODS_ROOT}/../Podfile.lock"
"${PODS_ROOT}/Manifest.lock --> 

${SRCROOT}/Podfile.lock"
"${SRCROOT}/Pods/Manifest.lock
