无法在Laravel 8中使用旧式工厂

如何解决无法在Laravel 8中使用旧式工厂

我正在将laravel 7.x项目升级到8。

我现在仍在使用遗留工厂，因为我有许多遗留工厂，并将它们用于测试和其他事情中，因此要永久地换成新的类结构，就需要花费时间。

问题是我似乎无法在本地运行有种子工厂的种子或测试。

我已经导入了新的laravel/legacy-factories，并在播种器上设置了名称空间，并更新了composer.json文件。但是每次我尝试运行播种机或测试时，我都会得到一个错误

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

我按照文档建议的那样从classmap中删除了composer.json，但在有或没有适当位置的情况下都进行了尝试。

我尝试完全删除所有缓存，并且不高兴地运行composer install。

还有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。

解决方法

我最终通过简单地从引导目录中删除packages.php和services.php文件来解决此问题，然后composer dump-autoload做到了。
