php - 调用未定义的方法 Illuminate\\Database\\Schema\\Blueprint::increments()

Question

我是 laravel 4 的新手，在我的第一个项目中，当我尝试迁移它时，我遇到了这个错误:

Migration table created successfully. {"error":{"type":"Symfony\Component\Debug\Exception\FatalErrorException","message":"Call to undefiend method Illuminate\Database\Schema\Blueprint::increments()","file":"foo","line:19"}}

这是我在 app\migration\2014_10_14_114343_add_cats_and_breeds_table.php 中的迁移代码:

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class AddCatsAndBreedsTable extends Migration {

public function up()
{
    Schema::create('cats', function($table){
        $table->increments('id');
        $table->string('name');
        $table->date('date_of_birth')->nullable();
        $table->integer('breed_id')->nullable();
        $table->timestamps();
    });

    Schema::create('breeds', function($table){
        $table->incremetns('id');
        $table->string('name');
    });
}


public function down()
{
    Schema::drop('cats');
    Schema::drop('breeds');
}

}

谁能帮我改正错误？

你打错了。

代替:

$table->incremetns('id');

应该是

$table->increments('id');
