php - 无法在 Laravel 6.5.1 上制作 "composer require laravel/ui --dev"

Question

我收到以下错误:

Can't make "composer require laravel/ui --dev" on laravel 6.5.1. I get an error "Your requirements could not be resolved to an installable set of packages.

问题1:

结论:删除 laravel/framework v6.5.1

结论:不要安装laravel/framework v6.5.1

安装失败，将 ./composer.json 恢复为其原始内容。

在我的 composer.json

请帮忙。

Answer 1

laravel/ui 的第 2 版与 Laravel 的第 6 版不兼容，因此使用 composer require laravel/ui="1.*" --dev 安装第 1 版
