ios - Xcode 链接器错误 : File not found

Question

我目前在我的 Xcode 项目中使用 cocoapods 为我的应用程序创建一个 google 登录按钮，在再次完成教程步骤后，构建时仍然出现错误。以下是构建时显示的错误消息。如果您能帮助解决此问题，我们将不胜感激。

简短的错误消息(在控制台错误消息的末尾)

ld: file not found: /Users/tarunaarora/Desktop/GunnOracleApplication/Pods/GoogleUtilities/Libraries/libGTM_NSData+zlib_external.a
clang: error: linker command failed with exit code 1 (use -v to see invocation)
