将Laravel 7升级为8

Question

我正在使用Laravel 7.3，由于插件需要，需要更新到8

我正在阅读文档，但由于我是一个像英语一样的傻瓜，在计算方面我有一些错误和问题

首先，我遵循这个：

更新composer.json文件中的以下依赖项：

guzzlehttp/guzzle to ^7.0.1
facade/ignition to ^2.3.6
laravel/framework to ^8.0
laravel/ui to ^3.0
nunomaduro/collision to ^5.0
phpunit/phpunit to ^9.0

似乎还不够，因为这是composer更新的返回

julien@julien-Lenovo-IdeaPad-S340-15IWL:/var/www/html/adopte$ composer update

- Root composer.json requires laravel/framework ^8.0 -> satisfiable by laravel/framework[v8.0.0, ..., 8.x-dev].
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades, and removals for packages currently locked to specific versions.

所以我读了完整的文档，上面写着：

https://github.com/laravel/horizon/blob/master/UPGRADE.mdphp artisan horizon:发布返回

There are no commands defined in the "horizon" namespace.  

我假装文档的其余部分是特定于某些程序的，但我想不是我。

有人能帮我吗？

Answer 1

结论：不要安装cviebrock/雄辩的可击7.0.2(冲突分析结果(

https://github.com/cviebrock/eloquent-sluggable

它在包文档中明确指出，您需要laravel 8的包版本8。

所以改变

"cviebrock/eloquent-sluggable": "^8.0",

laravel文档包含升级laravel本身的说明。如果你也在使用其他软件包，那么也需要通过寻找其他兼容版本的来升级这些软件包
