Docker golang包导入错误：导入路径不以主机名开头

问题描述

我试图测试码头和去项目。这是我的码头文件

  FROM golang 
 
 ARG app_env 
 ENV APP_ENV $ app_env 
 
 COPY ./ /go/src/github.com/user/myProject/app 
 WORKDIR /go/src/github.com/user/myProject/app 
 
 
 
 RUN go get ./ 
 RUN go build 
 
如果[$ {APP_ENV} =生产]; CMD; \ 
然后\ 
 app; \ 
 else \ 
 go get github.com/pilu/fresh&& \ 
新鲜; \ 
 fi 
 EXPOSE 8080 
  

运行良好。然后我在我的go程序中添加了一个testpack包。

  package main 
 
 import（
fmt
time
testpack
）
 
 var now = time.Now（）
 var election = time。日期（2016，time.November，8，0，0，0，time.UTC）
 func main（）{
 //获取选举日期和现在之间的期限
 untilElection： = election.Sub（now）
 //以毫微秒为单位获得持续时间
 toNanoseconds：= tillElection.Nanoseconds（）
 //计算小时到纳秒
小时：= toNanoseconds / 3600000000000 
余数：= toNanoseconds％3600000000000 
 //从剩余小时数中得出分钟数
分钟数：=余数/ 60000000000 
余数=余数％60000000000 
 //从余数中派生秒分钟
秒：=剩余/ 1000000000 
 //计算天数并获得剩余小时数
天：=小时/ 24 
 hoursLeft：=小时％24 
 
 fmt.Printf（\\\
直到2016年美国总统大选？\\\\\\％天，％，小时，％，分钟， $ p> 
 
 
现在我运行=> docker build ./
 
 
 
我收到错误
 
 
 
包testpack：无法识别的导入路径testpack（导入路径不以hostname开头）
 
 
我试过这个，但无法解析
 
 
 
任何帮助都是值得赞赏的。
解决方案
很明显，它试图从Internet上加载它，因为它没有在你的GOPATH中找到testpack。
 
 
 
向我们展示您的GOPATH设置或您将测试包复制到的位置，除了说我错过了这些我就可以告诉您。 HTTPS ：//golang.org/cmd/go/#hdr-Relative_import_pathsrel =nofollow noreferrer> https://golang.org/cmd/go/#hdr-Relative_import_paths  
 
 
 
试试 
 
 
 
 
  import./testpack\" 
 
 
将Dockerfile中的GOPATH设置为/ go
 
  importgithub.com/user/myProject/app/testpack / code> 
 
 
 
I am trying to test docker and go project. Here is my dockerfile
FROM golang

ARG app_env
ENV APP_ENV $app_env

COPY ./ /go/src/github.com/user/myProject/app
WORKDIR /go/src/github.com/user/myProject/app



RUN go get ./
RUN go build

CMD if [ ${APP_ENV} = production ]; \
then \
app; \
else \
go get github.com/pilu/fresh && \
fresh; \
fi  
EXPOSE 8080
It runs fine. Then i added a package "testpack" to my go program.
package main

import(
"fmt"
"time"
"testpack"
)

var now = time.Now()
var election = time.Date(2016, time.November, 8, 0, 0, 0, 0, time.UTC)
func main() {
 //get duration between election date and now
tillElection := election.Sub(now)
//get duration in nanoseconds
toNanoseconds := tillElection.Nanoseconds()
//calculate hours from toNanoseconds
hours := toNanoseconds/3600000000000
remainder := toNanoseconds%3600000000000
//derive minutes from remainder of hours
minutes := remainder/60000000000
remainder = remainder%60000000000
//derive seconds from remainder of minutes
seconds := remainder/1000000000 
//calculate days and get hours left from remainder
days := hours/24
hoursLeft := hours%24

fmt.Printf("\nHow long until the 2016 U.S. Presidential election?\n\n%v Days %v Hours %v Minutes %v Seconds\n\n", days, hoursLeft, minutes, seconds)

}
Now i ran=>  docker build ./
I am getting an error 
package testpack: unrecognized import path "testpack" (import path does not begin with hostname)
I tried this Error 'import path does not begin with hostname' when building docker with local package  but couldn't resolve
Any help is appreciated.
 解决方案 
It is obviously trying to load it from the Internet because it isn't finding "testpack" in your GOPATH.
You didn't show us your GOPATH setting or where you copied "testpack" to, so other than saying "It's missing" that's all I can tell you.
Read https://golang.org/cmd/go/#hdr-Relative_import_paths
Try either
import "./testpack"
Set GOPATH to "/go" in your Dockerfile
import "github.com/user/myProject/app/testpack"
