/**
* Database configuration class.
*
* You can specify multiple configurations for production, development and testing.
*
* datasource => The name of a supported datasource; valid options are as follows:
* Database/Mysql - MySQL 4 & 5,
* Database/Sqlite - SQLite (PHP5 only),
* Database/Postgres - PostgreSQL 7 and higher,
* Database/Sqlserver - Microsoft SQL Server 2005 and higher
*
* You can add custom database datasources (or override existing datasources) by adding the
* appropriate file to app/Model/Datasource/Database. Datasources should be named 'MyDatasource.php',
*
*
* persistent => true / false
* Determines whether or not the database should use a persistent connection
*
* host =>
* the host you connect to the database. To add a socket or port number, use 'port' => #
*
* prefix =>
* Uses the given prefix for all the tables in this database. This setting can be overridden
* on a per-table basis with the Model::$tablePrefix property.
*
* schema =>
* For Postgres/Sqlserver specifies which schema you would like to use the tables in.
* Postgres defaults to 'public'. For Sqlserver, it defaults to empty and use
* the connected user's default schema (typically 'dbo').
*
* encoding =>
* For MySQL, Postgres specifies the character encoding to use when connecting to the
* database. Uses database default not specified.
*
* unix_socket =>
* For MySQL to connect via socket specify the `unix_socket` parameter instead of `host` and `port`
*
* settings =>
* Array of key/value pairs, on connection it executes SET statements for each pair
* For MySQL : http://dev.mysql.com/doc/refman/5.6/en/set-statement.html
* For Postgres : http://www.postgresql.org/docs/9.2/static/sql-set.html
* For Sql Server : http://msdn.microsoft.com/en-us/library/ms190356.aspx

第97行：
connected = ConnectionManager::getDataSource('default');
你能告诉我可能有什么问题吗？
答案 0 :(得分：1)
删除所有CakePHP内容并再次上传整个框架并且它可以正常工作。当我收到此错误时，文件没有完全上传。
