Golang: go runs old versions of main.go after changes-CodePudding

When I run main.go, code change does not appear.

func main() {
    // Commenting out below line works correctly
    // after commenting out and access to "/" path returns server error
    http.HandleFunc("/", handler.IndexHandler)

    // but
    // Commenting out below line or Add some code in the AuthGoogleHandler function
    // seems not to appear in actual behavior
    // Even after commenting out, "/auth/google" works for some reason.
    http.HandleFunc("/auth/google", handler.AuthGoogleHandler)


    http.ListenAndServe(fmt.Sprintf(":%s", os.Getenv("SERVER_PORT")), nil)
}

I have developed same url endpoints in another go projects, so I wonder if it related.

My trial is below

make sure I run correct main.go file
rebooting my PC
run by Goland and terminal

Reference golang: go run is always running old code even after changes

CodePudding user response：

I found out the cause. It was browser cache problem. I run main.go and access my localhost url with chrome secret mode works correctly

Thank you for the people who answered.

CodePudding user response：

You can try a force a rebuild of all packages with the following:

go build -a

also this can do the same:

go clean
go build
