Describe the bug

A clear and concise description of what the bug.

autocompletion does not appear to be working and my import is being flagged as "could not import..."

A clear and concise description of what you expected to happen.

no errors, working autocompletion

Steps to reproduce the behavior:

This was a fresh vscode install and a brand new go project.

scottjg@MacBook-Pro server % cat go.mod 
module github.com/rewatchtv/remote/server

go 1.14

require github.com/gorilla/websocket v1.4.2
scottjg@MacBook-Pro server % cat main.go
package main

import (
        "flag"

        "github.com/gorilla/websocket"
)

var addr = flag.String("addr", "localhost:8080", "http service address")

var upgrader = websocket.Upgrader{} // use default options

func main() {
}

after creating the project, and building it with go build (so dependencies are downloaded), i installed the go extension and chose to install all the tools when prompted by dialogs in vscode. I don't have a GOPATH set, but this is a go module project, so i don't think it's needed? these are all default vscode settings set by the Go extension.

nevermind... eventually a dialog popped up saying that for go module projects to work, you have to open an editor window with the go.mod file at the root. weird that it didn't appear until i started randomly changing preferences, but it seems to be working.
