Pinning < 4.0.0 seems to prevent this.

swagger_spec_validation issue : Yelp/swagger_spec_validator#149

[tirkarthi]

This was an issue with jsonschema release 4.0.0 where python_requires was not honored. This is fixed in python-jsonschema/jsonschema@e61dcbc with 4.0.1 released and 4.0.0 yanked.

[kpfleming]

I'm still getting this with jsonschema 4.0.1 installed...

[tirkarthi]

Yelp/swagger_spec_validator#146 needs to be merged.

[dominiquesydow]

@tirkarthi, it seems like the problem is resolved, right?

[tirkarthi]

I guess so 2.7.4 has been released with the merged fix https://pypi.org/project/swagger-spec-validator/
