Heroku python-telegram-bot，但显示“ Modulenotfounderror：No模块命名为＆＃x27; Telegram＆＃x27; ＆quot

Question

我在Virtual-env上安装了Python-Telegram-bot，并通过从Telegram.ext Import *导入它，但它在Heroku上不起作用。我在Heroku控制台上运行python3 main.py，但我遇到了此错误：

Traceback (most recent call last):
  File "/app/main.py", line 2, in <module>
    from telegram.ext import *
ModuleNotFoundError: No module named 'telegram'
