Laravel 8 運行 composer require laravel/passport 時，您的要求無法解決為一組可安裝的軟件包

Question

這個問題有很多版本，但我還沒有找到任何處理這些特定包的版本。

我正在嘗試將 laravel 護照版本 10 安裝到我的 laravel 8 安裝中，當運行composer require laravel/passport我得到以下響應：

    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] <-我不明白這部分，它與“最低穩定性”有什么關系：“ dev”在我的作曲家.json？

無論如何，這是我的 composer.json：

        }
    },

            "App\\": "app/",
            "Database\\Factories\\": "database/factories/",
            "Database\\Seeders\\": "database/seeders/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "Tests\\": "tests/"
        }
    },
    "minimum-stability": "dev",
    "prefer-stable": true,
    "scripts": {
        "post-autoload-dump": [
            "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
            "@php artisan package:discover --ansi"
        ],
        "post-root-package-install": [
            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "@php artisan key:generate --ansi"
        ]
    }
}

編輯 1：我嘗試運行composer require --no-update laravel/passport並且當我運行composer update我得到以下錯誤（我雖然它可能提供額外的信息）：

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].

編輯 2：為了進一步解釋下面的答案，您必須刪除項目中的供應商文件夾和 composer.json 文件，然后運行composer install降級到 laravel 8. 之后，您可以運行composer require laravel/passport它會正確安裝

Answer 1

簡單做一件事

刪除composer.lock文件，然后安裝你需要的包

它對我有用...

Answer 2

將你的 Laravel 版本從 9 降級到 8

}

Answer 3

我能夠通過修改我的操作系統上的PHP PATH來解決這個問題，當時我正在使用帶有WampServer的windows 。

上面建議的更改可能會起作用，但是如果正在運行composer install命令，那是因為 App 已經存在並且正在下載其依賴項，因此更改上面建議的文件可能會導致應用程序運行出現問題。 我認為將PATH注釋更改為正確的 PHP 版本將起作用，在我的情況下： C:\wamp64\bin\php\php7.3.21有效。

Answer 4

只需刪除 composer.json 和 composer.lock 文件，它就可以解決問題:)

Answer 5

當我收到此錯誤時，我試圖安裝barryvdh/laravel-ide-helper 。 如此處所述，它需要 PHP 7.3+ 和Laravel 8.0+ ，但我的版本較低。 所以這是我遵循的步驟：

1. 刪除了composer.lock文件
2. 更改composer.json中 PHP 和 Laravel 的版本
3. Ran composer install它創建了一個新的composer.lock文件
4. 然后運行composer require barryvdh/laravel-ide-helper安裝成功
