CocoaPodsエラー diff: /../Podfile.lock: No such file or directory

以下のようなエラー。

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.

Pods.debug.xcconfigとPods.release.xcconfigをファイル自体消去してからpod installで直った。

消さずにpod installじゃ直らないなぁ。
