php - CakePHP SQLSTATE [HY000] [14]错误

我正在尝试将当前的CakePHP 2.x应用程序升级到3.x。

我修复了 namespace 和文件夹结构的问题。现在我有数据库问题。在测试服务器中，我创建了相同的MySQL数据库并向用户授予访问权限。然后，我更改了config\app.php配置文件。但是，当我尝试我的应用程序时，出现以下错误。有什么问题吗？似乎Cakephp尝试使用Sqlite，但我使用MySQL？

内部config\app.php

'Datasources' => [
    'default' => [
        'className' => 'Cake\Database\Connection',
        'driver' => 'Cake\Database\Driver\Mysql',
        'persistent' => false,
        'host' => 'localhost',
        /**
         * CakePHP will use the default DB port based on the driver selected
         * MySQL on MAMP uses port 8889, MAMP users will want to uncomment
         * the following line and set the port accordingly
         */
        //'port' => 'nonstandard_port_number',
        'username' => 'myuser',
        'password' => 'mypass',
        'database' => 'mydatabase',
        'encoding' => 'utf8',
        'timezone' => 'UTC',
        'cacheMetadata' => true,

        /**
         * Set identifier quoting to true if you are using reserved words or
         * special characters in your table or column names. Enabling this
         * setting will result in queries built using the Query Builder having
         * identifiers quoted when creating SQL. It should be noted that this
         * decreases performance because each query needs to be traversed and
         * manipulated before being executed.
         */
        'quoteIdentifiers' => false,
    ],
],

最佳答案

如果您稍微看一下堆栈跟踪，您会注意到这不是源于您的应用程序连接，而是源于DebugKit插件，该插件默认情况下使用SQLite来存储面板和请求详细信息，并且很可能是目标目录/文件不可写。
