導入錯誤：無法從“neo4j.v1”（/usr/local/lib/python3.7/site-packages/neo4j/v1/__init__.py）導入名稱“CypherError”

Question

我正在嘗試將圖形庫連接到 tiangolo/full-stack-fastapi-postgresql 項目。 但是每次我遇到導入錯誤時。 請告訴我，也許有人遇到過類似的問題。 后端啟動日志：

Checking for script in /app/prestart.sh
Running script /app/prestart.sh

INFO:__main__:Starting call to '__main__.init', this is the 1st time calling it.

ImportError: cannot import name 'CypherError' from 'neo4j.v1' (/usr/local/lib/python3.7/site-packages/neo4j/v1/__init__.py)

我調用的代碼：

import logging
from sqlalchemy.orm import Session

from app import crud, schemas
from app.core.config import settings
from app.dbase import base

from neomodel import db as neodb
from neomodel import config, install_all_labels

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)


def init_db(dbase: Session) -> None:
    user = crud.user.get_by_email(dbase, email=settings.FIRST_SUPERUSER)
    if not user:
        user_in = schemas.UserCreate(
            email=settings.FIRST_SUPERUSER,
            password=settings.FIRST_SUPERUSER_PASSWORD,
            is_superuser=True,
        )
        user = crud.user.create(dbase, obj_in=user_in)

        neodb.set_connection("bolt://neo4j:password@neo4j:7687")
        person = Profile(email=settings.FIRST_SUPERUSER)
        person.save()
        country = Country(name="Russia")
        country.save()
        person.country.connect(country)

Answer 1

Neomodel 的要求表明它需要 neo4j 3.0、3.1、3.2 或 3.3
