could not import github.com/sv-tools/openapi (no required module provides package "github.com/sv-tools/openapi")

> Everything have been moved to root folder. So, the import path is github.com/sv-tools/openapi

Can't import _openapi_ package. At the same time, the import of "github.com/sv-tools/openapi/spec" works fine. It seems there is a versioning issue.
