相关疑难解决方法(0)

我在运行bake命令时遇到问题.我认为它与mysql有关,但我没有在Stackoverflow上找到任何解决此错误的方法.这是我的app.php:

'Datasources' => [
        'default' => [
            'className' => 'Cake\Database\Connection',
            'driver' => 'Cake\Database\Driver\Mysql',
            'persistent' => false,
            'host' => 'localhost',

            //'port' => 'nonstandard_port_number',
            'username' => 'root',
            'password' => 'root',
            'database' => 'laboiterose',
            'encoding' => 'utf8',
            'timezone' => 'UTC',
            'cacheMetadata' => true,

请帮忙,我得到的错误是:
