ModuleNotFoundError：ubuntu 上没有名为“龙卷风”的模块

Question

当我尝试运行我的应用程序时，出现以下错误

Traceback (most recent call last):
  File "./app.py", line 32, in <module>
    from pushservices.bootstrap import init_messaging_agents
  File "/home/airnotifier/airnotifier/pushservices/bootstrap.py", line 2, in <module>
    from .apns import *
  File "/home/airnotifier/airnotifier/pushservices/apns.py", line 5, in <module>
    from util import json_encode
  File "/home/airnotifier/airnotifier/util.py", line 37, in <module>
    import tornado
ModuleNotFoundError: No module named 'tornado'

我试图运行这个命令来安装龙卷风

python3 -m pip install tornado

然后我收到以下消息

Requirement already satisfied: tornado in /usr/local/lib/python3.8/dist-packages (6.0.3)

后跟以下错误日志

谁能告诉我我该怎么做，有什么问题？

这是可能导致此问题的一种情况：您以用户身份执行pip install tornado但您以其他用户身份运行 tornado 项目。 对不起我糟糕的英语，希望你能理解
