我目前正在通过终端在Laravel中进行迁移，并且在尝试使用php artisan migration时出现了这两个错误；我将在下面打印错误：
Exception trace:
1 PDOException::("SQLSTATE[HY000]: General error: 3780 Referencing column 'room_id' and referenced column 'id' in foreign key constraint 'contacts_room_id_foreign' are incompatible.")
/Users/shaquilenoor/Desktop/chatapi/vendor/laravel/framework/src/Illuminate/Database/Connection.php:458
2 PDOStatement::execute()
/Users/shaquilenoor/Desktop/chatapi/vendor/laravel/framework/src/Illuminate/Database/Connection.php:458根据异常跟踪中包含的代码，问题似乎在以下代码中：
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateContactsTable extends Migration
{
public function up()
{
Schema::create('contacts', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('user1_id');
$table->unsignedInteger('user2_id');
$table->integer('room_id')->unique();
$table->timestamps();
$table->foreign('room_id')->references('id')->on('rooms');
$table->foreign('user1_id')->references('id')->on('users');
$table->foreign('user2_id')->references('id')->on('users');
});
}
public function down()
{
Schema::dropIfExists('contacts');
}
}关于如何解决的任何想法？
