go - 如何通过 'go mod' 分隔不同目录中的代码？

Question

我的源目录布局像

mywork/libA
mywork/libA/liba.go
mywork/libA/go.mod
mywork/progB
mywork/progB/go.mod
mywork/progB/progb.go

在 mywork/libA/目录中，我输入 go mod init example.com/mywork/liba .

在 mywork/progB/目录中，我输入 go mod init example.com/mywork/progb .

libA/liba.go

package liba
func Hi() string {      return "hi" }

libA/go.mod

module example.com/mywork/liba

go 1.13

progB/progb.go

package main
import "example.com/mywork/liba"
func main() { println("progb:", liba.Hi()) }

progB/go.mod

module example.com/mywork/progb

go 1.13

go build在 libA目录是可行的。但是 go build失败 progB并显示

build example.com/mywork/progb: cannot load example.com/mywork/liba: cannot find module providing package example.com/mywork/liba

如何纠正它？

Answer 1

progB/go.mod 应该在 https://github.com/golang/go/wiki/Modules#can-i-work-entirely-outside-of-vcs-on-my-local-filesystem 中添加 require 和 replace 语句

module example.com/mywork/progb

require example.com/mywork/liba v0.0.0

replace example.com/mywork/liba => ../libA

go 1.13
