Laravel 8 运行 Composer require laravel/passport 时，您的需求无法解析为一组可安装的包

Question

这个问题有很多版本，但我还没有找到任何处理这些特定包的版本。

我正在尝试将 laravel Passport 版本 10 安装到我的 laravel 8 安装中，运行时composer require laravel/passport我得到以下响应：

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

  Problem 1
    - laravel/passport[v10.0.1, ..., 10.x-dev] require illuminate/auth ^8.2 -> found illuminate/auth[v8.2.0, ..., 8.x-dev] but it conflicts with another require.
    - laravel/passport v10.0.0 requires illuminate/auth ^8.0 -> found illuminate/auth[v8.0.0, ..., 8.x-dev] but it conflicts with another require.
    - Root composer.json requires laravel/passport ^10.0 -> satisfiable by laravel/passport[v10.0.0, v10.0.1, 10.x-dev].


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

找到照亮/auth ^8.0 -> 找到照亮/auth[v8.0.0, ..., 8.x-dev] <- 我不明白这部分，它与“最小稳定性”有什么关系：“ dev”在我的composer.json 中？

不管怎样，这是我的composer.json：

        "post-create-project-cmd": [
            "@php artisan key:generate --ansi"
        ]
    }
}

编辑1：我尝试运行composer require --no-update laravel/passport，当我运行时composer update出现以下错误（虽然它可能提供额外的信息）：

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

  Problem 1
    - laravel/passport[v10.0.1, ..., 10.x-dev] require illuminate/support ^8.2 -> satisfiable by illuminate/support[v8.2.0, ..., 8.x-dev].
    - laravel/passport v10.0.0 requires illuminate/support ^8.0 -> satisfiable by illuminate/support[v8.0.0, ..., 8.x-dev].
    - Only one of these can be installed: illuminate/support[dev-master, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev], laravel/framework[dev-master]. laravel/framework replaces illuminate/support and thus 
cannot coexist with it.
    - laravel/framework 9.x-dev is an alias of laravel/framework dev-master and thus requires it to be installed too.
    - Root composer.json requires laravel/framework ^9.0 -> satisfiable by laravel/framework[9.x-dev (alias of dev-master)].
    - Root composer.json requires laravel/passport ^10.0 -> satisfiable by laravel/passport[v10.0.0, v10.0.1, 10.x-dev].

编辑2：为了进一步解释下面的答案，您必须删除项目中的供应商文件夹和composer.json文件，然后运行composer install以降级到laravel 8。之后您可以运行composer require laravel/passport并且它将正确安装

Answer 1

简单的做一件事

删除composer.lock文件，然后安装所需的包

它对我有用...

Answer 2

将 Laravel 版本从 9 降级到 8
