imdbpy - 无法访问 SQL 数据库

Question

我已经安装了 IMDbPY 并通过 IMDb 文件和 imdb2py 脚本创建了一个数据库。现在我无法在我的脚本中使用该数据库。当我尝试使用数据库时，出现以下错误:

>>> from imdb import IMDb  
>>> i = IMDb('sql', uri='sqlite:/home/user/random/mov.db', useORM='sqlalchemy,sqlobject')

Answer 1

尝试使用指定完整路径的 URI。这样的事情应该有效:

sqlite:///home/user/random/mov.db

注意三重斜杠。
