关闭严格模式：

修改 app/database.php 文件中 mysql 参数，改动如下：

'mysql' => [
	'driver' => 'mysql',
	'host' => env('DB_HOST', '127.0.0.1'),
	'port' => env('DB_PORT', '3306'),
	'database' => env('DB_DATABASE', 'forge'),
	'username' => env('DB_USERNAME', 'forge'),
	'password' => env('DB_PASSWORD', ''),
	'unix_socket' => env('DB_SOCKET', ''),
	'charset' => 'utf8mb4',
	'collation' => 'utf8mb4_unicode_ci',
	'prefix' => '',
	'strict' => false, //重点是这里
	'engine' => null,
],
