我正在 AWS EC2 实例中使用其危险的 python 包运行 Flask 应用程序。

Traceback (most recent call last):
  File "run.py", line 4, in <module>
    app = create_app()
  File "/home/ubuntu/RHS_US/application/portal/__init__.py", line 29, in create_app
    from portal.users.routes import users
  File "/home/ubuntu/RHS_US/application/portal/users/routes.py", line 7, in <module>
    from portal.models import User
  File "/home/ubuntu/RHS_US/application/portal/models.py", line 7, in <module>
    from itsdangerous import TimedJSONWebSignatureSerializer as Serializer
ImportError: cannot import name 'TimedJSONWebSignatureSerializer' from 'itsdangerous' (/home/ubuntu/.local/lib/python3.7/site-packages/itsdangerous/__init__.py)

有解决办法吗？
