Laravel 7.2，安装作曲家，请勿安装xethron / migrations-generator

问题描述

我想从Laravel 7.2中的现有数据库创建迁移。 我在此link中找到了xethron / migrations-generator。 当我尝试安装它时，出现此错误：

我尝试composer require --dev "kitloong/laravel-migrations-generator"时遇到了类似的错误。

解决方法

正如您在https://packagist.org/packages/xethron/migrations-generator上看到的那样，该软件包非常旧，很可能与Laravel v7不兼容。

kitloong/laravel-migrations-generator是该软件包的分支，根据他们的发行说明，它应该可以在Laravel v8上使用。要使其正常运行，您必须先删除其他迁移生成器，然后仅安装分叉的软件包。
