Golang GUI fyne-io help set up?

I just can not configure the GUI fyne-io. go get fyne.io/fyne gave an error

package fyne.io/fyne: unrecognized import path "fyne.io/fyne" (https fetch: Get https://fyne.io/fyne?go- get=1: dial tcp: lookup fyne.io: no such host)

It’s good that IDE from JetBrains installed it from import

import ( "fyne.io/fyne/widget" "fyne.io/fyne/app" )

Then at go run there was an error

exec: “gcc”: executable file not found in %PATH%

Installation TDM-GCC helped solve the problem

And then I can not move.

package main

import (
    "fyne.io/fyne/widget"
    "fyne.io/fyne/app"
)

func main() {
    app := app.New()

    w := app.NewWindow("Hello")
    w.SetContent(widget.NewVBox(
        widget.NewLabel("Hello Fyne!"),
        widget.NewButton("Quit", func() {
            app.Quit()
        }),
    ))

    w.ShowAndRun()
}

After go run error

Issue 1 looked like a temporary issue in your DNS lookup - the IDE resolved it shortly after. Issue 2 well done on finding the solution. Issue 3 you’d be best placed raising a bug on the GitHub tracker[1] - with details of your windows version and hardware so that it can be worked on with you.
