终端错误信息:

#  from /Users/sunke/Desktop/Yep-master/Podfile:51
#  -------------------------------------------
#      target 'YepKitTests' do
>          inherit! :search_paths
#      end
#  -------------------------------------------

解决方案:
Open your Podfile and Remove Project_Tests block.
删除工程 test block,
然后更新CocoaPods ,调用命令

pod update --verbose --no-repo-update
