Php Laravel 迁移：未找到类

我正在将一个Laravel barebone项目部署到Microsoft Azure，但每当我try 执行php artisan migrate时，就会出现错误:

[2015-06-13 14:34:05]生产.错误:异常"Symfony\Component\Debug\exception\FatalErrorException"，在D:\home\site\vendor\laravel\framework\src\light\Database\Migrations\Migrator中显示消息"Class""not found".菲律宾:328

堆栈跟踪:

 #0 {main}  

有什么问题吗？非常感谢你

Migration Class

<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function(Blueprint $table)
        {
            $table->bigIncrements('id');
            $table->string('name', 50);
            $table->string('surname', 50);
            $table->bigInteger('telephone');
            $table->string('email', 50)->unique();
            $table->string('username', 50)->unique();
            $table->string('password', 50);
            $table->boolean('active')->default(FALSE);
            $table->string('email_confirmation_code', 6);
            $table->enum('notify', ['y', 'n'])->default('y');
            $table->rememberToken();
            $table->timestamps();
            
            $table->index('username');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('users');
    }
}
