pod 'AFNetworking','~> 2.0'
pod 'GoogleMaps'
pod 'MONActivityIndicatorView'
pod 'NYXImagesKit'
pod 'MagicalRecord'
pod 'FBSDKCoreKit'
pod 'FBSDKShareKit'
pod 'FBSDKLoginKit'
pod 'Countly'

问题是cocoapods 0.39正在将AFNetworking更新到版本2.5.4,这是错误的.最新版本是2.6.3另外facebook SDK更新到4.4(最新版本为4.8)等.

我试图删除Pods文件夹和.lock文件,但没有帮助

还试图清理cocoapods缓存但没有帮助：
