ImportError: cannot import name 'TypedDict' from 'typing_extensions'

Hypercorn 的問題，依賴沒有安裝全.

解決辦法 1：使用 Python 3.8

解決辦法 2: pip install typing_extensions

问题描述 在pip上更新了 nonebot ( nonebot/nonebot https://github.com/nonebot/nonebot )（pip install --upgrade nonebot），更新过程中同时将aiocqhttp更新到了版本1.4.0，Quart更新到了0.14.1，hypercorn更新到了版本0.11.2。然后试图运行nonebot，在import nonebot处报错。试图在python的互动式界面中输入import nonebot 或 import aiocqhttp 报相同的错误。见下面贴的报错信息。

复现方法 见上。

期望的行为 正常import相关库而不报错？

確保你的 typing_extensions 是最新版的 （3.10.0.0 ）

谢谢，之前装的版本貌似不是最新（3.7）。问题已解决
