使用具有典型目录结构的 go 模块，似乎无法正常工作

Question

So I created a simple test project to demonstrate the issue I'm having in a much larger code base here https://github.com/cleblanc189/test.go

.
├── go.mod
├── main.exe
├── main.go
├── server
│   ├── v1beta1
│   │   ├── foo.go
│   │   └── go.mod
│   └── v1ga
│       ├── foo.go
│       └── go.mod
└── service
    ├── v1beta1
    │   ├── foo.go
    │   └── go.mod
    └── v1ga
        ├── foo.go
        └── go.mod

I'd like to be able to reference service/v1beta1 from server/v1beta1 but I'm getting this error

go: test.go/src/server/v1beta1@v0.0.0 requires
        test.go/src/service/v1beta1@v0.0.0: unrecognized import path "test.go/src/service/v1beta1" (https fetch: Get https://test.go/src/ser
vice/v1beta1?go-get=1: dial tcp: lookup test.go: no such host)

In foo.go from server/v1beta1 I import like this svc "test.go/src/service/v1beta1"

and have a go.mod file like below;

require test.go/src/service/v1beta1 v0.0.0

replace test.go/src/service/v1beta1 => ../../service/v1beta1

When I try to cd src && go mod tidy I get that error above. Also if anyone knows should I even have a go.mod above the src directory?

Appreciate any help anyone can offer. This is maddening.

Answer 1

Your go.mod has to declare the module path/name, typically like this:

module test.go

Then all the import s in your code will be taken relative to that. When you import something relative to your declared module name, the go tool will automatically pick up the code from the right place locally.

Not sure where your src comes into play though... is everything in folder src ? See this post and accompanying code for a complete example you could start from.
