laravel/ui[v3.2.0, ..., 3.x-dev] 需要照明/控制台 ^8.0

Question

我尝试安装：

作曲家需要 laravel/ui

但我不断收到此错误：

laravel/ui[v3.2.0, ..., 3.x-dev] 需要照明/控制台 ^8.0 -> 找到照明/控制台[v8.0.0, ..., 8.x-dev] 但这些不是已加载，可能是因为它与另一个需求冲突。 - 根composer.json需要laravel/ui ^3.2 -> 可满足laravel/ui[v3.2.0, 3.x-dev]。 这是我的composer.json：

我是 Laravel 的初学者。希望有人提供解决方案。预先感谢。

Answer 1

我用的是这个：

composer require laravel/ui:^2.4

而不是

composer require laravel/ui

并且成功了！ 根据这个laravel文档[链接]：https://laravel.com/docs/7.x/frontend

Answer 2

根据 Laravel 框架文档使用此命令

Laravel 8.* 需要 laravel/ui 版本 3.4

composer require laravel/ui:^3.4

Laravel 7. 需要 laravel/ui 版本 2.4

composer require laravel/ui:^2.4

Laravel 6.* 需要特定的 laravel/ui 版本 1.0

composer require laravel/ui:^1.0 --dev

Laravel 7 UI 文档

Laravel 6 UI 文档

Answer 3

您必须使用以下方式更新您的软件包：

composer update

然后你就可以运行了:

composer require laravel/ui

Answer 4

您还可以尝试使用显式版本约束重新运行composer require，例如“composer require laravel/ui:*” 以确定是否有任何版本可安装
