pod》error:The dependency `` is not used in any concrete target

內容提要：

podfile升級之後到最新版本，pod裡的內容必須明確指出所用第三方庫的target，否則會出現The dependency `` is not used in any concrete target這樣的錯誤。

以下從三個步驟陳述：

1. Podfile升級

檢視pod版本：

pod --version

pod 升級（此時是升級到1.0.0.beta.2版本）：

sudo gem install cocoapods --pre

2. 錯誤內容：

我的Podfile的內容是：

platform :ios, '7.0'

pod 'ReactiveCocoa', '2.1.8'

pod 'objectiveflickr', '2.0.4'

pod 'LinqToObjectiveC', '2.0.0'

pod 'SDWebImage', '3.6'

pod install後出現錯誤The dependency `` is not used in any concrete target

複製程式碼

pod install
