Question

I get a golang project form github, I have inited go mod and modified relative import. but when execute go build main.go , error as follow:

build _/D_/myCode/jd_seckill-1/common: cannot find module for path _/D_/myCode/jd_seckill-1/common

This is go.mod that created after I executed go mod init jdSeckill

module jdSeckill

)

This is main.go have be modified by me

package main

import (
    "jdSeckill/common"    //   ../common   before modified
    "jdSeckill/conf"      //   ../conf     before modified
    "jdSeckill/jd_seckill"
    "errors"

Answer 1

Go's module functionality was designed for the public external modules. If you want to use local modules, you should use "replace" directive of go mod

See here - https://github.com/golang/go/wiki/Modules

Here is the example of the go mod replace:

module github.com/user/service

replace github.com/user/depservice => /Users/user/Projects/depservice

require (
    github.com/user/depservice v1.1.1
)
