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 mainimport (    "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：D:\Développement\golang\src\github.com\jpmonette\hello>go envset GOARCH=386set GOBIN=set GOCHAR=8set GOEXE=.exeset GOHOSTARCH=386set GOHOSTOS=windowsset GOOS=windowsset GOPATH=D:\Développement\golang\set GORACE=set GOROOT=C:\Goset GOTOOLDIR=C:\Go\pkg\tool\windows_386set CC=gccset GOGCCFLAGS=-g -O2 -m32 -mthreadsset CGO_ENABLED=1
