在Laravel8中安装Laravel/ui的问题

我正在尝试安装 laravel/ui，但出现此错误：

**Problem 1**
- laravel/tinker is locked to version v2.5.0 and an update of this package was not requested.
- laravel/tinker v2.5.0 requires illuminate/console ^8.0 -> found illuminate/console[v8.0.0, ...,     8.x-dev] but these were not loaded, likely because it conflicts with another require.
  **Problem 2**
- laravel/ui[v3.0.0, ..., 3.x-dev] require illuminate/console ^8.0 -> found illuminate/console[v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.
- Root composer.json requires laravel/ui ^3.0 -> satisfiable by laravel/ui[v3.0.0, v3.1.0, 3.x-dev].

我试过：

composer require laravel/ui "^3.0" --dev

并且：

composer require laravel/ui  --dev

我总是得到同样的错误。

注意：我使用的是最新版本：Laravel 8。
