$ go version
go version go1.10 linux/amd64

Does this issue reproduce with the latest release?

no

What did you do?

  1. Install go1.10
  2. go get -u golang.org/x/tools/...
  3. go run main.go
    main.go:
package main

import (
        "fmt"
        "golang.org/x/tools/go/packages"
)

func main() {
        var conf packages.Config
        _, err := packages.Load(&conf, "file=main.go")
        if err != nil {
                fmt.Println(err)
        }
}

What did you expect to see?

no output

What did you see instead?

bash-4.2$ go run main.go 
unsupported version of go: exit status 2: flag provided but not defined: -compiled
usage: list [-e] [-f format] [-json] [build flags] [packages]

Hello, we have a policy of only supporting the current and previous Go releases. As of today, that's Go 1.12 and Go 1.11. So this is "working as intended".

Hopefully you're able to work around this by using an older version of tools, or a newer version of Go.

Thanks!
Michael
