Unknown/unsupported Swagger version to validate against:

[aegixx]

Doesn't seem to be picking up the Swagger version correctly (notice no version is reported).

I get this even when loading https://github.com/OAI/OpenAPI-Specification/blob/master/examples/v2.0/json/petstore-minimal.json

     Failure/Error: subject { Apivore::SwaggerChecker.instance_for('/swagger.json') }
     RuntimeError:

Related to #64 though I get the error also when loading https://github.com/westfieldlabs/apivore/blob/master/spec/data/01_sample2.0.json

Running apivore (1.6.2)

Are you changing the default rspec host used for requests from "www.example.com" to something else? This is the only change I've made and I'm having this issue. I think it must be a bug in apivore, it should support changing the host.
