InvalidArgumentException：未配置数据库[s_request]

Question

我正在尝试将多个迁移表迁移到多个数据库中，但出现这种错误：

 // If the configuration doesn't exist, we'll throw an exception and bail. 149| $connections = $this->app['config']['database.connections']; 
150| 
151| if (is_null($config = Arr::get($connections, $name))) { > 
152| throw new InvalidArgumentException("Database [{$name}] not configured."); 153| } 
154| 
155| return (new ConfigurationUrlParser) 
156| ->parseConfiguration($config); Exception trace: 1 Illuminate\Database\DatabaseManager::configuration("s_request") /home/dipu/A1pathshala/vendor/laravel/framework/src/Illuminate/Database/DatabaseManager.php:115 2 Illuminate\Database\DatabaseManager::makeConnection("s_request") /home/dipu/A1pathshala/vendor/laravel/framework/src/Illuminate/Database/DatabaseManager.php:86 Please use the argument -v to see more details.

这是我的配置：

。env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=A1pathshala
DB_USERNAME=root
DB_PASSWORD=

DB_CONNECTION_SECOND=mysql2
DB_HOST_SECOND=127.0.0.1
DB_PORT_SECOND=3306
DB_DATABASE_SECOND=school_request
DB_USERNAME_SECOND=root
DB_PASSWORD_SECOND=

database.php

    connection=>[

                'options' => extension_loaded('pdo_mysql') ? array_filter([

                ]) : [],
            ],

            //secondary database
            'mysql2' => [

在迁移表中使用此。

 public function up()
    {
        Schema::connection('mysql2')->create('schools', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::connection('mysql2')->dropIfExists('schools');
    }
}

并且正在迁移使用此

php artisan migrate --database=mysql2
