[Python] TypeError: duplicate base class TimeoutError (aioredis)

Problem

Recently, I have been working on my fast-api project using a virtual environment.

However, I ran up with this error:

class TimeoutError(asyncio.TimeoutError, builtins.TimeoutError, RedisError):

TypeError: duplicate base class TimeoutError

I found out that this error was due to aioredis not being supported anymore and being replaced by redis library.

Solution

1. pip uninstall aioredis

2. pip install "redis>=4.2.0rc1"

3. In “.venv/Lib/site-packages/fastapi_mail/email_utils/email_check.py”:

   change import redis to from redis import asyncio as aioredis
