根因分析
Go要求main包中有main()函数用于可执行程序,但编译器仅在引用时检查init()函数;当包期望一个未定义的init()函数时会出现此错误。
English
Go requires a main() function in the main package for executable programs, but the compiler specifically checks for init() functions only when they are referenced; this error occurs when a package expects an init() function that is not defined.
官方文档

-
Ensure the main package has a main() function defined with the correct signature: func main()
-
If the package is a library (non-main), change the package declaration to something other than main
无效尝试
常见但无效的做法:
-
60% 失败
This only works if the package actually requires init() for initialization; often the real issue is a missing main() function or import cycle.
-
95% 失败
Test files are not compiled in normal builds; this hides the real problem.
