Windows 7 및 Python 3.3에서 pylint 실행 시도

Question

이 일반적인 질문은 새로운 것이 아니라는 것을 알고 있었지만 내 개인적인 문제로 보입니다.

필자는 Python 3.3 용 Windows 7에서 pylint를 설치하려고합니다. (예, 지원되지 않지만 사용 가능하다는 것을 알고 있습니다. 제 동료가 그랬기 때문에 슬프게도 알려진 문제에 대한 해결책이 효과가 없었습니다. 내 PC - 그는 Windows 8 ...)

현재 Python 3.3을 설치했으며 처음에는 pip를 통해 pylint를 설치하려고했으나 실패했습니다.

수색 내 동료와 일부 회담이 대답 가져 : No luck pip-installing pylint for Python 3

나는이 지침 pylint를 설치하려면 관리를하지만, dependecies (logilab-astng) 중 하나가 실패했습니다.

setup.py 스크립트를 검사하고 "2to3"변환이 내 컴퓨터에서 실행되지 않는다는 것을 알았습니다. (나는 경로 문제로 생각합니다) - 변환을 재구성하여 실행했습니다.

이후 모든 설치 과정은 (pylint는 logilab-astng는 logilab - 일반)는 "성공"종료 -하지만 난 pylint를 시작하면 나는이 메시지를 가지고 : 나는 당신의 아이디어를 기대하고

Answer 1

문제는 pylint에서 사용되는 ast 표현을 포함하는 logilab-astng는 아직 python 3.3에 도입 된 "yieldfrom"노드를 지원하지 않는다는 것입니다.

당신은이 문제를 해결해야한다, 패치 아래에 시도 할 수 있습니다 :

diff --git a/rebuilder.py b/rebuilder.py 
--- a/rebuilder.py 
+++ b/rebuilder.py

     newnode.set_line_info(newnode.last_child())
