우분투에 모듈을 찾을 수 없지만 (설치되어 있음)

Question

lxml 모듈을 설치 한 후 내 스크립트가 Ubuntu 10.10의 원래 버전에서 성공적으로 실행됩니다. (파이썬 2.6.6)

그래서 필자는 pyhton2.7 (소스 코드에서)을 수동으로 컴파일하고 설치했다. 나는 (소스 코드에서)를 python2.6.7에 반환 한

Error: ImportError: No module named lxml 

하지만 오류가 발생하는 유지 : 내 스크립트는 더 이상 일을하지 않았다. 올바른 파이썬 버전 (2.6.7)이 호출됩니다.

참고 : 오류가 발생한 후 번거롭게 python-lxml 패키지를 제거하고 다시 설치했습니다. 오류가 남아 있습니다 :

파이썬이 모듈을 찾는 데 어떤 종류의 마법 스크립트를 실행해야합니까?

Answer 1

당신이

/usr/bin/python ./RunScriptPython.py 

를 실행하려고 수있는, 내 진단 (아래) 올바른지 테스트하려면 (그것은 작동합니다 .)

---

출력 내용에 유의하십시오.

import site # precompiled from /usr/local/lib/python2.6/site.pyc 

가져 오기는 /usr/local/lib/python2.6에 있습니다. 이것은 이 아니고 우분투 시스템의 기본 버전 인 python입니다. 이것은 로컬 설치입니다.

python-lxml 패키지를 설치하면 /usr/lib/python2.6/에 설치되며/usr 대신/usr/bin에있는 Python의 Ubuntu 시스템 기본 버전으로 액세스 할 수 있습니다/local/bin 버전의 python을 실행중인 것처럼 보입니다.

어떤 이유로 든/usr/local 버전의 Python이 필요하지 않다면 가장 쉬운 해결책은 제거하고 Python의/usr/bin 버전을 사용하는 것입니다.

Answer 2

Aptitude는 배포 표준 Python (2.6.6)에 대해서만 python-lxml을 설치합니다. 수동으로 설치된 Python에 lxml을 사용하려면 각 Python 버전에 대해 lxml을 설치해야합니다.

this SO answer을 읽으십시오. 가장 쉬운 방법은 easy_install 또는 pip을 사용하는 것입니다 (둘 다 PyPI에서 직접 패키지를 다운로드 할 수 있습니다. aptitude와 비슷하지만 Python 패키지의 경우).

그래서, 핍 또는 배포 설치 한 후 : 무슨 일이 생긴 무엇

easy_install-2.7 lxml 
/path/to/python2.7 /path/to/pip install lxml
