【问题描述】：
这个问题有很多版本，但我没有找到任何处理这些特定包的版本。
我正在尝试将 laravel 护照版本 10 安装到我的 laravel 8 安装中，
运行composer require laravel/passport 时，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Illumination/auth ^8.0 -> 找到Illuminate/auth[v8.0.0, ..., 8.x-dev]
无论如何，这是我的 composer.json：

编辑 1：
我尝试运行composer require --no-update laravel/passport，当我运行composer update 时出现以下错误（虽然它可能会提供额外信息）：
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：
要进一步解释下面的答案，您必须删除项目中的 vendor 文件夹和 composer.json 文件，然后运行 composer install 以降级到 laravel 8。
之后你可以运行composer require laravel/passport，它会正确安装
【问题讨论】：
-
"laravel/framework": "^9.0",? 9？ -
好问题，我还没有编辑composer.json，我不知道这是怎么回事，我把它改成8吗？它会破坏什么吗？编辑：我改变了，我得到了一个额外的错误，所以是的，它必须在开发版本上：
Root composer.json requires laravel/framework ^8.0, found laravel/framework[v8.0.0, ..., 8.x-dev] but the package is fixed to 9.x-dev (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
