MacPorts 설치 후 Python에 대한 올바른 PATH 얻기

방금 MacPorts와 함께 설치한 일부 Python 라이브러리(PIL, psycopg2)를 가져올 수 없습니다. 이 포럼을 살펴보고 이 문제를 해결하기 PATH위해 변수를 조정하려고 시도했지만 ~/.bash_profile작동하지 않았습니다.

PIL과 psycopg2의 위치를 PATH​​. 터미널이 MacPorts에서 설치한 버전이 아닌
에서 Python 버전을 사용하고 있다는 것을 알고 있습니다 ./usr/local/bin/opt/local/bin

터미널에서 Python을 사용할 때 PIL 및 psycopg2가 sys.path에 있는지 확인하려면 MacPorts 버전의 Python을 사용해야 합니까? MacPorts 버전의 Python으로 전환해야 합니까, 아니면 더 많은 문제가 발생합니까?

도움이 될 경우를 대비해 추가 사실을 알려드리겠습니다.

PIL 및 psycopg2는 다음 위치에 설치됩니다./opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages

which python보고/usr/bin/python

$ echo $PATH반환합니다(쉽게 읽을 수 있도록 각 경로를 분리했습니다).

:/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/
:/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages
:/opt/local/bin

:/usr/bin
:/bin
:/usr/sbin
:/sbin
:/usr/local/bin
:/usr/local/git/bin
:/usr/X11/bin
:/opt/local/bin

Python에서는 >>> sys.path다음을 반환합니다.

위의 내용 중 하나라도 어리석거나 잘못된 생각으로 보인다면 어떤 비판이나 의견도 환영합니다. 나는 이 모든 것을 처음 접했습니다. 감사해요!

MacBook Pro에서 OSX 10.6.5를 실행하고 터미널에서 Python 2.6.1을 호출합니다.

답변1

Python을 설치한 후 'notes' 명령을 사용하십시오(python26을 설치한 버전으로 변경).

$ port notes python26

설치 후 권장 사항에는 몇 가지 변형이 표시됩니다.

python26 has the following notes:
  To fully complete your installation and make python 2.6 the default,  please
  run:
    sudo port install python_select
    sudo port select python python26

기본 Python을 설치 python_select한 다음 선택 해야 합니다 . python26그런 다음 실제로 MacPorts(예: port install py26-psycopg2 py26-pil)를 사용하여 PIL 및 pyscopg2를 설치했다면 지정할 필요가 없습니다.아무것안에 PYTHONPATH. 또한 /opt/local/Library/Frameworks/…. PATH​이 작업을 수행한 후에 which python는 를 반환해야 합니다 /opt/local/bin/python. MacPorts에 의해 설치된 Python 포트는 이미 MacPorts Python /opt/local/Library/Frameworks/Python.framework에 있습니다 . MacPorts Python 패키지에 대한 지식이 없는 sys.pathSystem Python(예: )을 사용했기 때문에 이전에는 해당 항목을 찾지 못했습니다 ./usr/bin/python

답변2

나생각하다나는 내 질문에 대한 답을 알아냈다. 포함하도록 ~/.bash_profile 파일을 편집했습니다.

export PYTHONPATH=

그런 다음 기존 경로를 모두 추가했습니다 sys.path.

export PYTHONPATH=/Library/Frameworks/SQLite3.framework/Versions/3/Python:/Library/Python/2.6/site-packages/numpy-override:/Library/Frameworks/GDAL.framework/Versions/1.7/Python/site-packages:/Library/Frameworks/cairo.framework/Versions/1/Python:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python26.zip:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-darwin:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac/lib-scriptpackages:/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-old:/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload:/Library/Python/2.6/site-packages:/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/PyObjC:/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/wx-2.8-mac-unicode:/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/:/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages:

그런 다음 MacPorts가 항목을 설치한 디렉토리에 경로를 추가했습니다.

/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/:/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages:

이제 sys.path를 인쇄하면 MacPorts 설치 디렉터리의 경로가 포함됩니다.

지금

>>> import PIL

그리고

>>> import psycopg2

잘 작동합니다.
