What version of Go are you using (go version)?

$ go version
go version go1.12.5 darwin/amd64

Does this issue reproduce with the latest release?

I'm using 1.12.5 which is the latest release according to this page. I just ran go get -u golang.org/x/tools/cmd/gopls so presumably gopls is up to date.

What operating system and processor architecture are you using (go env)?

What did you do?

Put in file main.go in an otherwise empty directory:

package main

import "fmt"

func main() {
	fmt.Println("Hello World")
}

Then run:

% gopls check main.go

What did you expect to see?

Some diagnostics, maybe. Not an error. (I don't actually use this command specifically; I narrowed down the error from an LSP failure in Emacs.)

What did you see instead?

In module mode you need a go.mod file for gopls to load the package properly. I think there are plans to improve the messaging to make this more clear.
