無法在 Laravel 6.x 中安裝 laravel/ui

Question

我已經建立了一個新的 Laravel 6 項目並且正在嘗試安裝一些軟件包。 到目前為止，我已經下載了核心包，現在我正在嘗試進行 Auth，但是當我嘗試安裝 laravel/ui 時，composer 給出了這樣的錯誤消息

Your requirements could not be resolved to an installable set of packages.

 Problem 1

- Installation request for laravel/framework (locked at v6.18.0, required as ^6.0) -> satisfiable by laravel/framework[v6.18.0].
- Installation request for laravel/ui ^2.0 -> satisfiable by laravel/ui[2.x-dev, v2.0.0, v2.0.1].

我該怎么做才能解決這個問題？

Answer 1

由於您的錯誤指示

laravel/ui 2.x-dev需要照明/文件系統 ^7.0 -> 照明/文件系統 [7.x-dev, v7.0.0, v7.0.1, v7.0.2, v7.0.3, v7.0.4] 可滿足。

您正在安裝依賴於Laravel 7 的Laravel ui 2.x ，這就是您收到此錯誤的原因。

要解決這個問題，您需要將項目升級到Laravel 7或需要安裝Laravel ui 1.x
