Ariadne is not compatible with graphql-core 3.1

Hi folks,

I’m hitting this error with the very example at https://www.starlette.io/

from starlette.applications import Starlette
from starlette.responses import JSONResponse
from starlette.routing import Route


async def homepage(request):
    return JSONResponse({'hello': 'world'})


app = Starlette(debug=True, routes=[
    Route('/', homepage),
])

  File "./example.py", line 1, in <module>
    from ariadne import QueryType, make_executable_schema
  File "x/lib/python3.8/site-packages/ariadne/__init__.py", line 11, in <module>
    from .graphql import graphql, graphql_sync, subscribe
  File "x/lib/python3.8/site-packages/ariadne/graphql.py", line 18, in <module>
    from graphql.validation.rules import RuleType

❯ python --version
Python 3.8.2

❯ pip freeze | grep "ariadne"
ariadne==0.10.0

❯ python -c "import graphql; print(graphql.__version__)"
3.1.0b2

Digging a bit:

Looks like this commit from graphql-python removed RuleType from graphql.validation.rules

Thanks!

GraphQL Core 3.1 has been released, so this task can land as part of Ariadne 0.12

@nikordaris I don’t think so. Can’t you create custom branch on your repo and update your project’s deps to use git URL in the meantime?
