CakePHP SQLSTATE[HY000][14] 错误

Question

我正在尝试将我当前的 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。现在我有数据库问题。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。会有什么问题？好像 Cakephp 尝试使用 Sqlite 但我使用 MySQL ?

里面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,
    ],
],

错误

如果您仔细观察堆栈跟踪，您会发现这并非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，以及大多数可能目标 directory/file 不可写。

Cookbook > DebugKit

[...]

DebugKit Storage

By default, DebugKit uses a small SQLite database in your application’s /tmp directory to store the panel data. If you’d like DebugKit to store its data elsewhere, you should define a debug_kit connection.

Database Configuration

By default DebugKit will store panel data into a SQLite database in your application’s tmp directory. If you cannot install pdo_sqlite, you can configure DebugKit to use a different database by defining a debug_kit connection in your config/app.php file.
