无法回滚Laravel迁移

Question

I've created a migration for CreateUserTable successfully.

<?php

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

class CreateUserTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('user', function(Blueprint $table)
        {
            $table->increments('id');
            $table->string('email')->unique;
            $table->string('password', 60);
            $table->timestamps();
        });
    }

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

}

but I'm not able to rollback:

$ php artisan migrate:rollback
{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","message":"Class 'CreateUserTable' not found","file":"C:\\xampp\\htdocs\\laravel\\vendor\\laravel\\framework\\src\\Illuminate\\Database\\Migrations\\Migrator.php","line":301}}

Someone suggested to run below but it give me an other error:

$ composer dump-autoload
Composer could not find the config file: C:\ProgramData\ComposerSetup\bin
To initialize a project, please create a composer.json file as described in the http://getcomposer.org/ "Getting Started" section

Any solution to rollback and avoid this second error related to composer.json? I'[m using Laravel 4 with fresh installation.

Rollback often requires you to run composer dumpautoload first. I've had the same problems in Laravel 5.1.

In your case dumpautoload should be in one word - this way it works for me.

And of course composer should be run in a folder that contains the composer.json file. This would be your Laravel project folder.
