不支持驱动程序[app.database]。 Laravel 5.1

Question

驱动程序[app.database]不支持。 Laravel 5.1

我已经克隆了公司项目的存储库，在尝试取消该项目时，我向自己抛出了以下错误，已经检查了连接参数，并且一切正常，

该错误与W7和Laravel 5.1有关。

config.databases.php 返回[

'fetch'=> PDO :: FETCH_CLASS，

'default'=> env（'DB_CONNECTION'，'mysql'），

'connections'=> [

'sqlite' => [
    'driver'   => 'sqlite',
    'database' => storage_path('database.sqlite'),
    'prefix'   => '',
],

'mysql' => [
    'driver'    => 'mysql',
    'host'      => env('DB_HOST', 'localhost'),
    'port'      => '4242',
    'database'  => env('DB_DATABASE', '***'),
    'username'  => env('DB_USERNAME', '***'),
    'password'  => env('DB_PASSWORD', ''),
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',

    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'charset'  => 'utf8',
    'prefix'   => '',
