Call to a member function connection() on null

问题描述

按照文档上一步步走下来的，但是好像数据库连接失败了

程序代码

查询代码

$name = Db::table('tb_park')->where('id', 1)->value('name');
return response("hello $name");

数据库配置文件

    // 默认数据库
    'default' => 'mysql',
    'mysql' => [
        'driver'      => 'mysql',
        'host'        => '127.0.0.1',
        'port'        => 3306,
        'database'    => 'test_park',
        'username'    => 'root',
        'password'    => '123456',
        'unix_socket' => '',
        'charset'     => 'utf8mb4',
        'collation'   => 'utf8mb4_general_ci',
        'prefix'      => '',
        'strict'      => true,
        'engine'      => null,
    ],
