migration - Laravel 4 迁移 - 未找到类

Question

这个问题现在已经解决了 - 我使用了以下内容:

而且，感谢 IRC，问题得到了解决。我被告知要跑

php composer.phar dump-autoload

这解决了我的问题。这可能与我奇怪的 Composer 设置有关。

我刚刚开始使用 Laravel 4 来完成一个 future 可能的项目，来自 Laravel 3。我首先使用 artisan 创建一个新的迁移 create_blogs_table:

php artisan migrate:make create_blogs_table --table=blogs --create

这生成了基本的迁移文件结构，然后我又填写了一些内容:

<?php

use Illuminate\Database\Migrations\Migration;

class CreateBlogsTable extends Migration
{

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('blogs', function($table)
        {
            $table->increments('id');
            $table->string('title');
            $table->text('description')->nullable();
            $table->integer('user_id')->unsigned();
            $table->timestamps();
        });
    }

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

我现在尝试再次使用 artisan 运行此迁移:

php artisan migrate --env=local

*注意我为扩展名为 .dev 的域设置了本地数据库连接

以前这可以正常工作(在 Laravel 3 中)，但是使用 Illuminate 我会收到此错误:

我已经检查过，database/migrations/文件夹肯定会自动加载。我不知道这个问题的原因可能是什么。在 IRC 上询问并在谷歌上搜索后，我仍然完全一无所知，所以希望有人可以帮助我。

提前致谢!

我在 xubuntu 上遇到了这个错误，并使用 sudo Composer dump-autoload 修复了它
