我的一次迁移没有在Laravel 4中使用php artisan命令运行

Question

I have several migrations I am running in Laravel 4. I use the php artisan migrate:rollback and php artisan migrate commands to populate the tables. Interestingly enough, one of my migrations has stopped working (cannot roll back). All of the others are working fine. I haven't changed anything to my knowledge.

The migration in question is named: 2013_06_19_050252_create_artists_table.php

And it looks like so:

    <?php

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

class CreateArtistsTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('artists', function(Blueprint $table) {
            $table->increments('id');
            $table->string('url_tag')->unique();
            $table->string('username');

            $table->timestamps();
        });
    }

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

}

I have no idea why this isn't working. Any ideas what could be going on?

When you have problems with your migrations, sometimes

php artisan migrate:refresh

But if your migrations are really broken, and it happens sometimes, you may have to delete all your database tables and then run php artisan migrate again.
