从 laravel 7 升级到 laravel 8

Question

我正在尝试从 laravel 7 升级到 8 错误我得到了错误

您的需求无法解决为一组可安装的软件包。

问题 1

- Conclusion: don't install laravel/framework v8.0.1 (conflict analysis result)
- Conclusion: don't install laravel/framework v8.0.2 (conflict analysis result)
- Conclusion: don't install laravel/framework v8.0.3 (conflict analysis result)
- Conclusion: don't install laravel/framework v8.33.0 (conflict analysis result)
- Conclusion: don't install laravel/framework v8.33.1 (conflict analysis result)
- laravel/horizon[v4.0.0, ..., v4.3.5] require illuminate/support ^7.0 -> satisfiable by illuminate/support[v7.0.0, ..., v7.30.4].
- Only one of these can be installed: illuminate/support[v5.0.0, ..., v5.8.36, v6.0.0, ..., v6.20.19, v7.0.0, ..., v7.30.4, v8.0.0, ..., v8.33.1], laravel/framework[v8.0.0, ..., v8.33.1]. laravel/framework replaces illuminate/support and thus cannot coexist with it.
- Root composer.json requires laravel/framework ^8.0 -> satisfiable by laravel/framework[v8.0.0, ..., v8.33.1].
- Root composer.json requires laravel/horizon ^4.0 -> satisfiable by laravel/horizon[v4.0.0, ..., v4.3.5].

使用选项 --with-all-dependencies (-W) 允许升级、降级和删除当前锁定到特定版本的软件包。

什么是错误，我该如何解决？

Answer 1

错误信息很清楚：

• laravel/horizo​​n[v4.0.0, ..., v4.3.5] 需要照明/支持 ^7.0 -> 可满足照明/支持[v7.0.0, ..., v7.30.4]。

您还需要更新所有其他软件包，例如 laravel/horizon。目前，您需要与 Laravel 8 不兼容的 v4。将该软件包更新为与 Laravel 8兼容的 v5。

Answer 2

我使用了composer install --ignore-platform-reqs，然后使用了php artisan serve，它对我有用。

但在我们开始之前，我已经将composer.json 中的 PHP 和 Laravel 更新为我需要的版本。
