You have either:

• out-of-date source repos which you can update with pod repo update or with pod install --repo-update.
• mistyped the name or version.
• not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, pod repo update does not happen on pod install by default.

这边跟新了pod ,并没有用，这个有什么解决办法吗
