go no required module provides package mux 错误

所以我有以下代码，

package main

import (

    "github.com/gorilla/mux"

)

func main() {

    router := mux.NewRouter()

}

当我运行时，它给出了以下错误 binapi.go:4:2: no required module provides package github.com/gorilla/mux; to add it: go get github.com/gorilla/mux，我该如何解决这个错误？我已经以各种可能的方式运行了 go get github.com/gorilla/mux 命令，并且我确定它已安装。不久前我发现了一个帖子，但它给出的命令不起作用。该命令是 go env -w GO111MODULE=auto 但它没有解决问题。

这是 go 环境
