Laravel 5播种器类不存在 [英] Laravel 5 Seeder Class Does Not Exist

问题描述

我重新安装了Laravel.我已经从GitHub存储库中的代码(该存储库是Laravel项目，相同版本(5.3))中移过.

I have a fresh Laravel installation. I have moved over code from a github repository that is a Laravel project, same version (5.3).

一切正常，但出于某种原因数据库种子无法运行.

Everything works fine, except for some reason the database seeds wont' run.

例如，我可以从新的Laravel安装中的github加载的迁移中迁移，就像我首先将迁移推送到github的服务器上一样.

For example, I can migrate from the github loaded migrations in the new Laravel installation, just as I would on the server that pushed the migrations to github in the first place.

但是我不能做php artisan db:seed，这意味着我美丽的小数据库是空的！ >:(

But I can't do php artisan db:seed, which means my beautiful little database is empty! >:(

我得到: ReflectionException类不存在

我尝试过的事情:

1. php artisan optimize
2. php artisan clear:cache
3. composer clearcache
4. composer dump-autoload

1. php artisan optimize
2. php artisan clear:cache
3. composer clearcache
4. composer dump-autoload

没有一个能解决我的问题. DatabaseSeeder中的所有内容均拼写正确，并且存在-do-类，它们在我的其他服务器上也可以正常工作，并且再次感谢Github，此全新安装现在具有与我的原始服务器相同的所有文件.

None of which have solved my problem. Everything in DatabaseSeeder is spelled correctly and the classes -do- exist, they work fine on my other server, and again, this fresh install now has all the same files as my origin server, thanks to Github.

DatabaseSeeder.php:

DatabaseSeeder.php:

<?php

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $this->call(UserTableSeeder::class);
    }
}

推荐答案

尝试运行

composer dump-autoload

尤其是如果您最近编辑了种子文件的名称

especially if you have recently edited the name of your seeder file
