Laravel 8 运行 composer require laravel/passport 时，您的要求无法解决为一组可安装的软件包

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 护照版本 10 安装到我的 laravel 8 安装中，当运行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Illumination/auth ^8.0 -> 找到Illumination/auth[v8.0.0, ..., 8.x-dev] <-我不明白这部分，它与“最低稳定性”有什么关系：“ dev”在我的作曲家.json？

无论如何，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并且当我运行composer update我得到以下错误（我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降级到 laravel 8. 之后，您可以运行composer require laravel/passport它会正确安装

Answer 1

简单做一件事

删除composer.lock文件，然后安装你需要的包

它对我有用...

Answer 2

将你的 Laravel 版本从 9 降级到 8

Answer 3

我能够通过修改我的操作系统上的PHP PATH来解决这个问题，当时我正在使用带有WampServer的windows 。

上面建议的更改可能会起作用，但是如果正在运行composer install命令，那是因为 App 已经存在并且正在下载其依赖项，因此更改上面建议的文件可能会导致应用程序运行出现问题。 我认为将PATH注释更改为正确的 PHP 版本将起作用，在我的情况下： C:\wamp64\bin\php\php7.3.21有效。

Answer 4

只需删除 composer.json 和 composer.lock 文件，它就可以解决问题:)

Answer 5

当我收到此错误时，我试图安装barryvdh/laravel-ide-helper 。 如此处所述，它需要 PHP 7.3+ 和Laravel 8.0+ ，但我的版本较低。 所以这是我遵循的步骤：

1. 删除了composer.lock文件
2. 更改composer.json中 PHP 和 Laravel 的版本
3. Ran composer install它创建了一个新的composer.lock文件
4. 然后运行composer require barryvdh/laravel-ide-helper安装成功
