Error when importing flask_graphql

[sciencehope]

Unable to import this library into my project. I always get an ImportError even if I create a new project with only one import.

My code api.py

from http.client import HTTPException
from multiprocessing import AuthenticationError
import os
from flask import Flask, request, jsonify, abort
from sqlalchemy import exc
import json
from flask_cors import CORS
from graphene import ObjectType, String, Schema
from flask_graphql import GraphQLView

app = Flask(__name__)

My requirements.txt In the beginning, I specify the version of each library, but there was an error. To solve the error, I removed the FLask-GraphQL because it is in conflict with other graphene dependency. As it said, _could not import flaskgraphql I remove graphene version and specify the last version in the Flask-GraphQL so that my project use the last version of this library and solve the dependency conflict with graphene. But always the same error.

Flask == 2.2.2
Flask-SQLAlchemy == 3.0.2
Jinja2 == 3.1.2
pylint == 2.15.9
Flask-Cors == 3.0.10
graphene  #For graphql python support
Flask-GraphQL == 2.0.1

I have the same issue. I think it has to do with collections.MutableMapping is moved to collections.abc.MutableMapping: https://stackoverflow.com/questions/70870041/cannot-import-name-mutablemapping-from-collections

Any workaround or patches?

For people following tutorials and still landing here, use this instead of flask_graphql:

from graphql_server.flask import GraphQLView
