失败-预期的“包装”，找到“ EOF”

Question

I've been having a hard time trying to execute a simple golang program in a virtual machine powered by vagrant. These are the relevant fields of my go env:

GOARCH="amd64"
GOPATH="/usr/local/src/go"
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/linux_amd64"

This is the program I'm trying to execute ( located in /usr/local/src/go/program ):

package program

import (
    "fmt"
)

func main() {
    fmt.Print("Aloha")
}

This, the output that I get:

main.go:4:5:
/usr/local/go/src/fmt/doc.go:1:1: expected 'package', found 'EOF'
package runtime:
/usr/local/go/src/runtime/alg.go:1:1: expected 'package', found 'EOF'

Take into account that this is a completely fake program. The weird thing is that it totally works in a different environment. What am I missing here?

Thanks a lot!

The problem wasn't neither with GOROOT nor GOPATH. The go installation failed at some point, leaving the whole thing unstable ( files created but completely empty ). When provisioning the virtual machine again, the go module checked whether the files existed. As they did, it took by granted that the installation had already take place.

A clean up and fresh installation from scratch solved the problem.
