不能在 Laravel 8 中使用遗留工厂

【中文标题】不能在 Laravel 8 中使用遗留工厂

【英文标题】：Cannot use legacy factories in Laravel 8

【发布时间】：2021-01-23 15:53:08

【问题描述】：

我正在将我的 laravel 7.x 项目升级到 8。

我现在坚持使用遗留工厂，因为我有很多它们并且在测试和其他事情中使用它们，所以要花很长时间才能换成新的类结构。

问题是我似乎无法在本地运行我的播种机或测试（有旧工厂）。

我已导入新的 laravel/legacy-factories 并在我的播种机上设置命名空间并更新了 composer.json 文件。但是每次我尝试运行播种机或测试时都会出错

Unable to locate factory for [App\Models\User] (or any other model)

按照文档的建议，我从composer.json 中删除了classmap，但在有和没有的情况下都进行了尝试。

我尝试完全删除所有缓存并毫无乐趣地运行composer install。

其他人有这个问题吗？

更新 - 这是我的 composer.json 文件。一些行已被删除。

【问题讨论】：

你能发布你的composer.json吗？

@Jerodev 按要求添加。

【参考方案1】：

我最终设法解决了这个问题，只需从引导目录中删除 packages.php 和 services.php 文件，然后 composer dump-autoload 就成功了。
