: 나는 matplotlib.pyplot를 (단지하기 matplotlib되지 않음) 가져올 때마다, 나는 다음과 같은 오류가 발생합니다. Matplotlib은 캐노피 배포판에 있으므로 제대로 설치되었다고 가정 할 수 있습니다.

Answer 1

나는 똑같은 문제가 있었고 Enthought에게이 문제에 대한 도움을 요청했고 다음 해결책을 얻었다. (위에서 논평 한 Jonathan March로부터). 캐노피 도구 메뉴에서

, 캐노피 터미널 창을 열고 전화 :

이

enpkg --no-deps matplotlib 1.2.1 
enpkg --no-deps libpng 1.2.40 
enpkg --no-deps freetype 2.4.4 

분명히 문제가, 적어도 내 경우에 해당하기 matplotlib 1.3 OS X 10.6에없는 라이브러리를 참조 . 따라서 해결 방법은 matplotlib를 다운 그레이드하는 것입니다.
