How to fix this error "runtime.main: undefined main.init"
问题
尝试运行一个简单的hello world go程序返回一个错误。
# command-line-arguments
runtime.main: undefined: main.init
runtime.main: undefined: main.main
文件内容：
package main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}
main显然是定义好的，添加func init() {}也没有帮助。
无论是run命令还是build命令都会导致相同的错误。
go build hello_test.go
go run hello_test.go
英文:
Trying run a simple hello world go program returns an error.
# command-line-arguments
runtime.main: undefined: main.init
runtime.main: undefined: main.main
The file contents:
package main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}
main is obviously defined and adding func init() {} doesn't help.
Both the run and build commands result in the same error.
go build hello_test.go
go run hello_test.go

将hello_test.go重命名为hello.go，它应该按预期工作。以_test结尾的Go源文件是特殊的（用于go构建系统）。它们被保留给go test命令使用。
英文:
Rename hello_test.go to e.g. hello.go and it should work as expected. Go source files ending in _test are special (for the go build system). They're reserved for the go test command.
