Question

我删除了我的Web2Py应用程序中的所有目录，除了控制器，模型，视图和静态以尝试重置我的应用程序，因为我对我的数据库结构进行了一些更改，并认为迁移太麻烦了一个近乎空的数据库的新应用程序。

现在我在控制台中收到错误，说web2py无法打开数据库文件。网络界面给了我一张未知的票。

以下是来自控制台的消息：

DEBUG: connect attempt 4, connection error: Traceback (most recent call last):   File "E:\Programming\Python\web2py\gluon\dal.py", line 4736, in __init__
    self._adapter = ADAPTERS[self._dbname](*args)   File "E:\Programming\Python\web2py\gluon\dal.py", line 1655, in __init__
    self.pool_connection(connect)   File "E:\Programming\Python\web2py\gluon\dal.py", line 444, in pool_connection

    self.connection = f()   File "E:\Programming\Python\web2py\gluon\dal.py", line 1654, in connect
    return self.driver.Connection(dbpath, **driver_args) OperationalError: unable to open database file ERROR:web2py:Traceback (most recent call last):   File "E:\Programming\Python\web2py\gluon\restricted.py", line 204, in restrict ed

    raise RuntimeError, "Failure to connect, tried %d times:\n%s" % (attempts, t b) RuntimeError: Failure to connect, tried 5 times: Traceback (most recent call last):   File "E:\Programming\Python\web2py\gluon\dal.py", line 4736, in __init__
