mux.go:12: 找不到导入：“github.com/gorilla/context”`

Question

我正在尝试安装我的 Go 测试包，但我不断收到此错误：

D:\Developpement\golang\src\github.com\gorilla\mux\mux.go:12: can't find import: "github.com/gorilla/context"

这是我的代码：

package main

import (

    "github.com/gorilla/pat"

    "net/http"

)

func main() {

  mux := pat.New()

  mux.Get("/user/:name/profile", http.HandlerFunc(profile))

  http.Handle("/", mux)

  log.Println("Listening...")

  http.ListenAndServe(":3000", nil)

}

func profile(w http.ResponseWriter, r *http.Request) {

  params := r.URL.Query()

  name := params.Get(":name")

  w.Write([]byte("Hello " + name))

}

MyGOROOT指向 Go 的安装根目录和GOPATH我的工作区根目录。

编辑

这是输出go env：
