invalid version: module contains a go.mod file, so module path must match major version

Question

I want to import and use own public package github.com/Siiir/asserter in it's v2.0.0 version.

I've tried:

1. go get github.com/Siiir/asserter

but this has produced

"require github.com/Siiir/asserter v1.0.1 // indirect"

in "go.mod" file.

2. go get github.com/Siiir/asserter@v2.0.0

got:

go: github.com/Siiir/asserter@v2.0.0: invalid version: module contains a go.mod file, so module path must match major version ("github.com/Siiir/asserter/v2")

3. After reading https://golang.cafe/blog/how-to-upgrade-to-a-major-version-in-go.html I tried

   go get github.com/Siiir/asserter/v2/@v2.0.0

got:

go: github.com/Siiir/asserter@v2.0.0: invalid version: module contains a go.mod file, so module path must match major version ("github.com/Siiir/asserter/v2")

4. go get github.com/Siiir/asserter/v2

got:

go: module github.com/Siiir/asserter@upgrade found (v1.0.1), but does not contain package github.com/Siiir/asserter/v2

5. After reading https://github.com/golang/go/issues/35732 I tried go get github.com/Siiir/asserter@master

6. Technicue in Upgrade Go dependency module to a new major version

7. Many other ideas.

I've additionally read:

1. https://github.com/fauna/faunadb-go/issues/77
2. Installing a go module fails with `invalid: module contains a go.mod file, so major version must be compatible`

Honestly I'm tired with my own attempts and believe that problem is so reproductible that I get your help.

I'm using

go version go1.18.2 windows/amd64.

Answer 1

After reading @Volker comment I published v2.0.1 of my github.com/Siiir/asserter with module name fixed.

Now go get github.com/Siiir/asserter/v2 produces "require github.com/Siiir/asserter/v2 v2.0.1 // indirect" in go.mod file as expected.
