The version of CocoaPods used to generate the lockfile
Lin-MacBoo$ pod install
Analyzing dependencies
[!] The version of CocoaPods used to generate the lockfile (1.2.0) is higher than the version of the current executable (1.0.1). Incompatibility issues may arise.
[!] Unable to satisfy the following requirements:
- `GoogleMaps (~> 2.1.1)` required by `Podfile`
- `GoogleMaps (= 2.1.1)` required by `Podfile.lock`
None of your spec sources contain a spec satisfying the dependencies: `GoogleMaps (~> 2.1.1), GoogleMaps (= 2.1.1)`.
You have either:
* out-of-date source repos which you can update with `pod repo update`.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.
