aiogram ошибка при установке!python

скачал библиотеку aiogram, при помощи pip install aiogram Но при запуске выводит это.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\samael\AppData\Local\Programs\Python\Python36\lib\site-packages\aiogram\__init__.py", line 4, in <module>

В чем ошибка?
