Question

当我使用dev_appserver.py启动应用程序时，此导入工作正常

我正在尝试重构以使用Firestore and Go 1.13

app.go内容

package main
import (
    "net/http"
    "workout"
)

项目结构：

app.go  
|-- workout dir  
    |-- workout.go file that contains (package workout)

我从工作目录的根目录运行：
$运行* .go

app.go:15:2: cannot find package "workout" in any of:
    /usr/local/go/src/workout (from $GOROOT)
    /Users/X/go/src/workout (from $GOPATH)

$ go run *.go workout/*.go
named files must all be in one directory; have ./ and workout/
X@MacBook-Pro Thu Oct 31 10:48:13 ~/Dropbox/go/src/workoutNew

$ go build   
app.go:15:2: cannot find package "workout" in any of:
    /usr/local/go/src/workout (from $GOROOT)
    /Users/X/go/src/workout (from $GOPATH)

Answer 1

import (
 "workout"
)

这将尝试导入名为workout的stdlib程序包。

要导入workout软件包，应使用go mod init命名主软件包，例如：github.com/me/myapp，然后将workout软件包导入为{{ 1}}。

将github.com/me/myapp/workout导入为相对目录（“ ./workout”）也可以，但这不是推荐的方式。

Answer 2

您的GOPATH和GOROOT：

/usr/local/go/src/workout (from $GOROOT)
/Users/X/go/src/workout (from $GOPATH)

将工作文件夹移至：

$GOPATH/my-app/

my-app
|...app.go
    workout
    |...workout.go

更新导入：

package main
import (
    "net/http"
    "my-app/workout"
)

现在移至：

cd $GOPATH/my-app/

运行app.go：

go run app.go

为什么Go在项目子目录中找不到导入包？
