我使用Macports安裝了Pythong2.6,psycopg2和pgAdmin3。我的settings.py是:Django/Python初學者:執行python manage.py時出錯syncdb - psycopg2未找到
DATABASE_ENGINE = 'postgresql_psycopg2' # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
DATABASE_NAME = 'mysite' # Or path to database file if using sqlite3.
DATABASE_USER = 'postgres' # Not used with sqlite3.
DATABASE_PASSWORD = '' # Not used with sqlite3.
DATABASE_HOST = '' # Set to empty string for localhost. Not used with sqlite3.
DATABASE_PORT = '' # Set to empty string for default. Not used with sqlite3.
當我運行python manage.py執行syncdb我得到的錯誤是:
Traceback (most recent call last):

請注意,我在這個東西一個完整的初學者。我原本是一個PHP傢伙,正在嘗試用於一個小型個人項目的Python。我需要「打開」Postgres嗎?
此外,當我sudo的蟒蛇manage.py runserver命令8080 我得到這個錯誤:

請指引我。任何答覆將不勝感激。
謝謝,

我該怎麼做才能讓python在這個路徑中查找/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages而不是/Library/Frameworks/Python.framework/Versions /2.6/lib/python2.6/site-packages – wenbert 2009-09-05 12:40:30
您可以修改sys.path以添加您自己的搜索目錄。對於django,你應該在settings.py中執行此操作。查看我更新的帖子以獲取詳細信 – 2009-09-05 12:42:07
是否可以創建一個由Macports創建的python路徑的符號鏈接?基本上,我有這樣的東西:Python.framework - > /opt/local/Library/Frameworks/Python.framework – wenbert 2009-09-05 12:54:46
