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。

我修复了命名空间和文件夹结构问题。现在我遇到了数据库问题。在我的测试服务器中，我创建了相同的 MySQL 数据库并授予用户访问权限。然后我就改变了config\app.php配置文件。但是当我尝试我的应用程序时，我收到以下错误。会出现什么问题呢？看起来 Cakephp 尝试使用 Sqlite 但我使用 MySQL ？

Inside 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,
    ],

如果您仔细观察堆栈跟踪，您会发现这并不是源于您的应用程序连接，而是源于 DebugKit 插件，该插件默认使用 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。

调试套件存储

默认情况下，DebugKit 在应用程序中使用一个小型 SQLite 数据库/tmp存储面板数据的目录。如果您希望 DebugKit 将其数据存储在其他地方，您应该定义一个debug_kit联系。

数据库配置

默认情况下，DebugKit 会将面板数据存储到应用程序的 SQLite 数据库中。tmp目录。如果无法安装pdo_sqlite，您可以通过定义一个来配置 DebugKit 使用不同的数据库debug_kit连接在你的config/app.php file.
