laravel-8 : Why i cannot install Laravel/Breeze

Question

当我尝试安装 laravel Breeze 时，使用命令 composer require laravel/breeze --dev ，它给了我这个错误:

Using version ^1.2 for laravel/breeze
./composer.json has been updated
Running composer update laravel/breeze
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/breeze[v1.2.0, ..., 1.x-dev] require illuminate/filesystem ^8.42 -> found illuminate/filesystem[v8.42.0, v8.42.1, v8.43.0, 8.x-dev] but it conflicts with another require.
    - Root composer.json requires laravel/breeze ^1.2 -> satisfiable by laravel/breeze[v1.2.0, v1.2.1, 1.x-dev].


Installation failed, reverting ./composer.json and ./composer.lock to their original content.

我当前的 Laravel 版本: laravel8 .
我正在尝试在现有应用程序上添加用户的身份验证 session 。
我的 composer.json 文件 :

{
    "name": "laravel/laravel",
    "type": "project",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",

Answer 1

您需要更新列出的依赖项 here
也许您不会在 composer.json 中找到“laravel/ui”，如果是这种情况，请手动将其添加为来自父“require”的属性。
然后你必须保存文件并在终端上运行命令:composer update以下是我的 composer.json 文件以供引用:
