這是我的主文件（server.go）：package mainimport (    "net/http"    "routes")func main() {    http.HandleFunc("/", routes.Handler)    http.ListenAndServe(":8000", nil)}我的路由模塊在同一目錄中：package routesfunc Handler(w http.ResponseWriter, r *http.Request) {    // stuff...}當我運行時，go run server.go我收到此錯誤：server.go:6:5: cannot find package "routes" in any of:    /usr/local/Cellar/go/1.6/libexec/src/routes (from $GOROOT)    ~/server/src/routes (from $GOPATH)當我將代碼routes.go放入我的server.go文件時，它運行良好。我無法導入模塊。我試過將$GOPATH變量設置為我的當前目錄，我試過重新排列我的項目目錄以模仿這里的目錄。我的選擇不多了。奇怪的是，一種被如此廣泛采用的語言，關于如何做幾乎所有其他語言都相對容易的事情的文檔如此糟糕。請幫我弄清楚我做錯了什么。更新：這是輸出 go envGOARCH="amd64"GOBIN=""GOEXE=""GOHOSTARCH="amd64"GOHOSTOS="darwin"GOOS="darwin"GOPATH="/Users/me/server"GORACE=""GOROOT="/usr/local/Cellar/go/1.6/libexec"GOTOOLDIR="/usr/local/Cellar/go/1.6/libexec/pkg/tool/darwin_amd64"GO15VENDOREXPERIMENT="1"CC="clang"GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"CXX="clang++"CGO_ENABLED="1"
