如何在golang中使用本地包？ [重复]

Question

This question already has an answer here:

• Error “can't load package: package my_prog: found packages my_prog and main” 3 answers

Here are two .go files.

├── lib.go
└── main.go

The lib.go has a package libtest.

$ cat lib.go 

package libtest

import (
    "fmt"
)

func TestLibFunc() {
    fmt.Println("This is test library function")
}

The main.go has a package main.

$ cat main.go
package main

import (
    "libtest"
)

func main() {
    libtest.TestLibFunc()
}

When I tried to build them, but it's failed.

$ go build *.go
can't load package: package main: found packages libtest (lib.go) and main (main.go) in /Users/dev/work/tmp/local-package

How can I use local packages in main package?

Answer 1

You need to put each package in a separate sub-directory. So your directory structure so put lib.go in project/lib and main.go in project/cmd. It should then work.
