others-[from java to go] How to solve 'can not find module ,working directory is not part of a module' problem when doing hello world with Go
Problem
In this post, I would demo how to solve the problem as follows when I develop a helloworld program with golang:
can't load package: cannot find module providing package bswen.com/goinaction/code/chapter2/test: working directory is not part of a module
Environments
The environments are as follows:
- go version: go version go1.14.2 darwin/amd64
- GOROOT: /usr/local/go
- GOPATH: /Users/me/GoProjects/src
- IDE: Intellij Idea Ultimate 2019.3 with go plugin
My project is located at $GOPATH/bswen.com/goinaction/code/chatper2/test
The code
The code is as follows:
package main
import "fmt"
func main() {
fmt.Println("hello world")
}
Run the code and get error
When I run the above the code, I get this error:
can't load package: cannot find module providing package bswen.com/goinaction/code/chapter2/test: working directory is not part of a module
How to solve the problem
I think there maybe a module problem with my project, so I execute this command to init my module:
go mod init bswen.com/goinaction/code/chapter2/test
Then I got this file go.mod in the directory $GOPATH/bswen.com/goinaction/code/chatper2/test, the content is:
module bswen.com/goinaction/code/chapter2/test
go 1.14
Then I rerun my helloworld, I got this:
hello world
Process finished with exit code 0
