[python] 거의 모든 라이브러리를 설치하는 pip 문제

거의 모든 것을 설치하기 위해 pip를 사용하는 데 어려움이 있습니다. 나는 코딩을 처음 접했기 때문에 이것이 내가 잘못하고있는 일이라고 생각하고 내가 필요한 대부분의 작업을 수행하기 위해 easy_install을 선택했지만 일반적으로 작동했습니다. 그러나 이제 nltk 라이브러리를 다운로드하려고하는데 둘 다 작업이 완료되지 않았습니다.

나는 들어 가려고했다

sudo pip install nltk

그러나 다음과 같은 응답을 받았습니다.

--easy_install installed fragments of the library and the code ran into trouble very quickly upon trying to run it.

이 문제에 대한 의견이 있으십니까? 나는 pip를 작동 시키거나 그 동안 문제를 해결할 수있는 방법에 대한 피드백을 정말 고맙게 생각합니다.
