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

问题描述

我有一个全新的 Laravel 安装.我已经从一个 Laravel 项目的 github 存储库中转移了代码，版本相同 (5.3).

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，但由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，我可以在新的 Laravel 安装中从 github 加载的迁移中迁移，就像我在最初将迁移推送到 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，这意味着我漂亮的小数据库是空的！>:(

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:

1. php 工匠优化
2. php artisan clear:cache
3. 作曲家清除缓存
4. 作曲家转储自动加载

这些都没有解决我的问题.DatabaseSeeder 中的所有内容都拼写正确，并且类 - 确实存在，它们在我的其他服务器上工作正常，而且，由于 Github，这个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 IlluminateDatabaseSeeder;

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

推荐答案

试运行

composer dump-autoload

尤其是如果您最近编辑了播种器文件的名称

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