Question

对于golang项目，我在单独的文件夹中有一些软件包，这会变得有些大。我一直在尝试创建单独的程序包，但不会被goimports检测到

GOPATH="/home/malek/go:/home/malek/Desktop/Workspace"
GORACE=""
GOROOT="/usr/local/go"

我的目录就是这样

Workspace -> src -> application -> utility -> math.go

在我的math.go文件夹中，我有软件包实用程序

但是当我尝试执行import "application/utility"或尝试将main.go文件（位于应用程序文件夹中）中math.go文件中的公共函数包括在内时，我会得到未定义...

我在做什么错了？

您尚未为我们提供具体步骤来重现您的问题。我没问题。 goimports -w main.go有效。例如，

application/main.go在goimports -w main.go之前：

package main

import (
    "fmt"
)

func main() {
    fmt.Println(utility.PiE())
}

application/utility/math.go：

package utility

import "math"

func PiE() float64 { return math.Pi * math.E }

命令：

#
cd $HOME
cd $HOME/Desktop/Workspace
rm -f src/application/application
cp src/application/main.bak src/application/main.go
tree
cd $HOME/Desktop/Workspace/src/
cat application/utility/math.go
cd application
export GOPATH=$HOME/gopath:$HOME/Desktop/Workspace
go env GOPATH
cat main.go
go build -a
goimports -w main.go
cat main.go
go build -a && ./application
#

输出：

~$ #
~$ cd $HOME
~$ cd $HOME/Desktop/Workspace
~/Desktop/Workspace$ rm -f src/application/application
~/Desktop/Workspace$ cp src/application/main.bak src/application/main.go
~/Desktop/Workspace$ tree
.

    └── application
        ├── main.bak
        ├── main.go
        └── utility

~/Desktop/Workspace$ cd $HOME/Desktop/Workspace/src/
~/Desktop/Workspace/src$ cat application/utility/math.go
package utility

import "math"

func PiE() float64 { return math.Pi * math.E }
~/Desktop/Workspace/src$ cd application
~/Desktop/Workspace/src/application$ export GOPATH=$HOME/gopath:$HOME/Desktop/Workspace
~/Desktop/Workspace/src/application$ go env GOPATH
/home/peter/gopath:/home/peter/Desktop/Workspace
~/Desktop/Workspace/src/application$ cat main.go
package main

import (
    "fmt"
)

func main() {
    fmt.Println(utility.PiE())
}
~/Desktop/Workspace/src/application$ go build -a
# application
./main.go:8:14: undefined: utility
~/Desktop/Workspace/src/application$ goimports -w main.go
~/Desktop/Workspace/src/application$ cat main.go
package main

import (
    "application/utility"
    "fmt"
)

func main() {
    fmt.Println(utility.PiE())
}
~/Desktop/Workspace/src/application$ go build -a && ./application
8.539734222673568
~/Desktop/Workspace/src/application$ #

application/main.go在goimports -w main.go之后：

package main

import (
    "application/utility"
    "fmt"
)

func main() {
    fmt.Println(utility.PiE())
}

goimports未检测到本地软件包
