是什么导致这个行走错误?

当我运行我的应用程序时,在推进中出现此错误:

PropelException: Unable to open PDO connection [wrapped: SQLSTATE[HY000] [14] unable to open database file]

我已经尝试了所有我能想到的,但是无法弄清楚是什么导致了这个问题。

我的build.properties是:

propel.project = LinkCannon2

# The Propel driver to use for generating SQL, etc.
propel.database = sqlite

# This must be a PDO DSN
propel.database.url = sqlite://Users/GMan/Public/Source/LinkCannon2/test/data/LinkCannon2TestDB.sq3

propel.addGenericMutators = true 

我的runtime-conf.xml是:

<propel>
  <datasources default="LinkCannon2">
   <datasource id="LinkCannon2"> <!-- this ID must match <database name=""> in schema.xml -->
    <adapter>sqlite</adapter> <!-- sqlite, mysql, myssql, oracle, or pgsql -->
    <connection>
     <classname>DebugPDO</classname>
     <dsn>sqlite://localhost///Users/GMan/Public/Source/LinkCannon2/test/data/LinkCannon2TestDB.sq3</dsn>
    </connection>
   </datasource>
