Laravel迁移表已经存在，但我想添加新的而不是旧的

我之前创建了用户表。现在，我创建了一个新的迁移，以在我的架构中创建新的书籍表。当我尝试运行该命令时

php artisan migrate

它显示：

[Illuminate\Database\QueryException]
SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' alre
ady exists (SQL: create table `users` (`id` int unsigned not null auto_incr
ement primary key, `username` varchar(255) not null, `email` varchar(255) n
ot null, `password` varchar(255) not null, `created_at` timestamp default 0
 not null, `updated_at` timestamp default 0 not null) default character set
 utf8 collate utf8_unicode_ci)

这是我的新迁移表：

<?php

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

class CreateBooksTable extends Migration {
    public function up()
    {
        Schema::create('books', function(Blueprint $table)
        {
            $table->increments('id');
            $table->string('name');
            $table->string('auther');
            $table->string('area');
            $table->timestamps();
        });
    }

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

如何摆脱错误？
