我正在尝试从laravel 7升级到8的错误，我得到了错误

无法将您的需求解析为一组可安装的软件包。

- 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）允许对当前锁定到特定版本的包进行升级、降级和删除。

错误消息非常清楚：

• Laravel/Horizon[v4.0.0,...,v4.3.5]需要照明/支持|^7.0->可由照明/支持[v7.0.0,...,v7.30.4]满足。

您还需要更新所有其他包，如laravel/horizon。当前，您需要的v4与Laravel8不兼容。将该包更新到与Laravel8兼容的v5。
