graphql-core v3?

[GinTR1k]

Hello!

Is there any plan to update graphql-core dependency to the latest version?

[hyusetiawan]

would love to know about this as well

Hey there, to add some context here - graphql-ws is now incompatible with graphql-core included in graphene and graphql-server. I've discussed this a bit over here: https://app.slack.com/client/TBFTZEULB/CBG1GAB42/thread/CBG1GAB42-1605717933.051400

Attempting to install the following packages:

graphene = "==3.0.0b2"
graphql-server = {extras = ["aiohttp"], version = "==3.0.0b2"}
graphql-ws = "==0.3.1"

Results in:

pipenv install graphql-ws==0.3.1

fwiw, using pip instead of pipenv results in graphql-ws installing but it is then incompatible at the code-API layer:

I was hoping there was a better answer here. I am building a GraphQL backend in Python, but this package is not compatible with graphql-core
