Protobuf/objectivec/GPBWellKnownTypes.h:44:10: fatal error: 'google/protobuf/Any.pbobjc.h' file not found

I met this problem , and how to solve it,   when I mad a pod Framework , integrated Protobuf by "pod 'Protobuf' " by editting 'podspec file'and run the command 'pod lib lint xxx.podspec'. Counld anyone give me an idea to get it over? waiting for helpping from God. [smile]
