GO – 本地导入不起作用

我是golang的新手，我想构build我的第一个简单的Web应用程序。 每次我想build立我的源，我得到一个错误的locale import "./controllers" in non-local package" 。

这是我的文件夹结构：

 goTest ├── Dockerfile ├── controllers │  └── IndexController.go └── main.go 

main.go文件：

 package main import ( "github.com/julienschmidt/httprouter" "net/http" "log" "./controllers" ) func main() { router := httprouter.New() router.GET("/", IndexController) log.Fatal(http.ListenAndServe(":8080", router)) } 

IndexController.go文件：

 package controllers import ( "fmt" ) func IndexController(w http.ResponseWriter, r *http.Request, ps httprouter.Params) error { fmt.Fprintf(w, "Hi %s!", r.URL.Path[1:]) } 

我的Dockerfile文件（从https://hub.docker.com/_/golang/复制）：

 FROM golang:1.8 WORKDIR /go/src/app COPY . . RUN go-wrapper download # "go get -d -v ./..." RUN go-wrapper install # "go install -v ./..." EXPOSE 8080 CMD ["app"] 

docker和去build设命令：

docker build -t my-golang-app .

至less在控制台输出：

 Sending build context to Docker daemon 4.608kB Step 1/7 : FROM golang:1.8 ---> b2063493320d Step 2/7 : WORKDIR /go/src/app ---> Using cache ---> 86d4df9fceaa Step 3/7 : COPY . . ---> 282286e66939 Removing intermediate container fe3c0686729a Step 4/7 : RUN go-wrapper download # "go get -d -v ./..." ---> Running in f34b5a5ef0de + exec go get -v -d github.com/julienschmidt/httprouter (download) main.go:7:5: local import "./controllers" in non-local package The command '/bin/sh -c go-wrapper download # "go get -d -v ./..."' returned a non-zero code: 1

🤦♂️

我终于find了问题。 在main.go文件中，我必须导入app/controllers而不是./controllers因为在Dockerfile中path是/go/src/app 。
