how to import vscode path

I am receiving the following error from vscode when i try to edit a go file:

"Error loading workspace: You are outside of a module and outside of $GOPATH/src. If you are using modules, please open your editor to a directory in your module. If you believe this warning is incorrect, please file an issue: https://github.com/golang/go/issues/new."

My go path is set as follows: GOPATH=C:\Users\myusername\go

I have vscode and go working together just fine on other machines... but i cant figure out what is wrong here.

I am still new to go so i am a little confused as to what the point of the GOPATH is.

from the go docs its says: "The GOPATH environment variable specifies the location of your workspace"

and the for the definition of a workspace the docs say: "A workspace is a directory hierarchy with two directories at its root: "

so from what the docs are saying and what vscode is complaining about is that i have my code outside of the path "C:\Users\myusername\go"...

obviously go doesn't expect me to do all my work in the location "C:\Users\myusername\go" on my machine.

so what is it complaining about?

here is the output of my "gopls -rpc.trace -v check go_practice.go" command:

2021/04/21 16:05:23 Info:2021/04/21 16:05:23 go env for C:\projects\go_practice

(go version go version go1.16.3 windows/amd64)
(valid build configuration = false)
(build flags: [])
GOROOT=C:\Program Files\Go

GONOPROXY=
GOMOD=NUL
GOPRIVATE=
GOMODCACHE=C:\Users\username\go\pkg\mod
GONOSUMDB=
GOPATH=C:\Users\username\go

If you came here googling for this error:

error loading workspace you are outside of a module and outside of $GOPATH/src

This may mean that you have multiple go.mod files in this folder, and the Go extension refuses to work. You'll either have to remove these files (by renaming, perhaps), or initialize a multi-module go workspace

Working on go 1.19, what solved this issue for me is to put

export GO111MODULE=ON

on ~/.bash_profile file.

Make sure you restart vscode.

If you want to debug with vscode, make sure to put in your launch.json file

 "configurations": [
    {
        ......
        "env": {  
            "GO111MODULE": "on",
        }
    }

this happens because you should open directly open your project by vs-code not a parent directory.

If you have multiple go.mod file in one workspace, you can use the "go work" to add the folder.

it need Go 1.18+

  1. In the root path of the workspace
  2. $go work init
  3. $go work use [folder-name]

The go.work file will be generated automatically

example:

go work init
go work http_Todo <no need "./">

In the following is my testing project structure for reference: enter image description here

Maybe you have opened a directory with the following format in VSCode.

example dir
      |- project1
           |- main.go
           |- go.mod
           ...
      |- project2
           |- main.go
           |- go.mod
           ...
      |- project3
           |- main.go
           |- go.mod
           ...
...

Opening a directory containing multiple go.mod files will result in this error. The solution is to open only the project1 directory in VSCode, with only one go.mod file open.

You can initialize a so-called "go module" by running go mod init <name>, where name, usually, is your repository URL. (eg. github.com/user/repo)

This will generate a go.mod file. Read more about go modules here.
