laravel BadMethodCallException : Method Illuminate\Database\Schema\Blueprint::int does not exist.

laravel 执行时php artisan migrate时提示如下错误：

Migrating: 2019_01_26_173010_create_article_table

 BadMethodCallException  : Method Illuminate\Database\Schema\Blueprint::int does not exist.

查看此文件发现

$table->int('sort')->default(100); 

将int改为integer

$table->integer('sort')->default(100);
