라이브러리 실습에 자꾸 문제가 생겨요ㅠㅠ

가르쳐주신대로 cmd에서 라이브러리도 다 설치했는데,

from googletrans import Translator

dave = Translator()

word = dave.translate('안녕하세요.', dest='en', src='ko')

print (word.text)

이거 실행하면

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

      4 print (word.text)

AttributeError: 'NoneType' object has no attribute 'group'

이렇게 뜨네요ㅠㅠ

다른 연습문제들도 마찬가지에요!
