【问题描述】：
我在 Heroku 上部署了一个电报机器人（使用 Django），python 版本为 3.6.9 它运行良好，没有任何问题。 几个月后，我做了一些更改，在尝试再次部署时遇到了问题。 Heroku 不再支持 python 3.6.9。支持3.6.10 所以我用 python 3.6.10 设置了 venv，运行服务器后我仍然遇到同样的问题。 短问题：
from .callbackcontext import CallbackContext File
"/home/usr/bot-name/venv/lib/python3.6/site-packages/telegram/ext/callbackcontext.py"
, line 21, in <module> from telegram import Update
ImportError: cannot import name 'Update' from 'telegram'
(/home/usr/bot-name/venv/lib/python3.6/site-packages/telegram/init.py)
我也尝试过 python 3.7.6（Heroku 也支持它），但是在运行服务器后我遇到了同样的问题：
_python manage.py runserver

几个月后你正在尝试这个，你可能需要查看
python-telegram-bot库，它在这几个月里也做了很多改变 -
你现在有带有电报名称的应用程序吗？如果是，则必须将其重命名为另一个名称
