GoLand IDE not correctly compiling. How to setup correct paths?

Question

I am trying to setup GoLand correctly to be able to use it with Go.

I'm trying to run the follow simple HelloWorld go project.

package HelloWorldProject


import "fmt"

func main(){
    fmt.Printf("Hello")

    fmt.Printf("1+1 = ", 1+1)

}

This is my console's results:

GOROOT=/usr/local/Cellar/go/1.10/libexec #gosetup
GOPATH=/Users/jeanmac/go #gosetup
/usr/local/Cellar/go/1.10/libexec/bin/go build -i -o /private/var/folders/r5/rfwd1cqd4kv8cmh5gh_qxpvm0000gn/T/___Hello /Users/jeanmac/go/src/github.com/jpere547/HelloWorldProject/Hello.go #gosetup

Compilation finished with exit code 0

I am on Mac OS and I installed Go using Brew.

Results of brew info go:

go: stable 1.10 (bottled), HEAD

==> Requirements
Required: macOS >= 10.8 ✔
==> Options
--without-cgo
    Build without cgo (also disables race detector)
--without-race
    Build without race detector
--HEAD
    Install HEAD version
==> Caveats
A valid GOPATH is required to use the `go get` command.
If $GOPATH is not specified, $HOME/go will be used by default:
  https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
  export PATH=$PATH:/usr/local/opt/go/libexec/bin

The GoLand configurations is below:
GOROOT

GOPATH

Answer 1

When you do go build something.go or go isntall something.go that only builds/installs the go package to give you an executable. You will need to run that executable.

The easiest way to run simple Golang programs is simply use go run something.go that will run your go file.

As long as your GOPATH is correctly set it should work
