Class 'Users' 运行 artisan 迁移时未找到

Class 'Users' not found when running artisan migration

我正在尝试 运行

project$ php artisan migrate:refresh

但得到错误

[Symfony\Component\Debug\Exception\FatalErrorException]
Class 'Users' not found

为什么我需要 Users class?我已经有 app/User.php:

<?php namespace App;

use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

class User extends Model implements AuthenticatableContract, CanResetPasswordContract {

[...]

和我的迁移,database/migration/2015_05_27_143124_create_users_table:

<?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->increments('id');
            $table->string('username')->unique();
            [...]
            $table->string('password', 60);
            $table->rememberToken();
            $table->timestamps();
        });
    }

    [...]

我的config/auth.php还有'model' => 'App\User'。我试过 运行宁 project$ composer dump-autoload。正在定义 User class。为什么我需要 Users class?

已修复。我删除了我的数据库并继续创建了一个同名的新数据库,然后:

project$ php artisan migrate
Migration table created successfully.
