我想在我的項目上運行composer install時發生錯誤。象這樣的錯誤發出：作曲家安裝 - 您的要求無法解析爲可安裝的一組套件

[email protected]:~/Triplogic/tripologic-admin-laravel$ sudo composer install 
Loading composer repositories with package information

    Problem 1 
    - Installation request for symfony/event-dispatcher v4.0.1 -> satisfiable by symfony/event-dispatcher[v4.0.1]. 
    - symfony/event-dispatcher v4.0.1 requires php ^7.1.3 -> your PHP version (7.0.22) does not satisfy that requirement.

，我有我的composer.json文件是這樣的：

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

    },

     ], 
     "psr-4": { 
      "App\\": "app/" 
     }, 
     "files": [ 
      "app/Helper/HelperFunction.php" 
     ] 
    }, 
    "autoload-dev": { 
     "psr-4": { 
      "Tests\\": "tests/" 
     } 
    }, 
    "scripts": { 
     "post-root-package-install": [ 
      "php -r \"file_exists('.env') || copy('.env.example', '.env');\"" 
     ], 
     "post-create-project-cmd": [ 
      "php artisan key:generate" 
     ], 
     "post-install-cmd": [ 
      "Illuminate\\Foundation\\ComposerScripts::postInstall", 
      "php artisan optimize" 
     ], 
     "post-update-cmd": [ 
      "Illuminate\\Foundation\\ComposerScripts::postUpdate", 
      "php artisan optimize" 
     ] 
    }, 
    "config": { 
     "preferred-install": "dist", 
     "sort-packages": true, 
     "optimize-autoloader": true 
    } 
}

人誰可以幫我，這將是非常有益的。

_「symfony/event-dispatcher v4.0.1需要php^7.1.3 - >您的PHP版本（7.0.22）不滿足該要求」_ <=非常自我解釋？ –

第一點：不要使用root權限運行composer - 沒有必要，它只會在以後引發問題。

二點：此行顯示的所有內容：

symfony/event-dispatcher v4.0.1 requires php ^7.1.3 -> your PHP version (7.0.22) does not satisfy that requirement.

所以：你要安裝的Symfony V4需要在V7.1.3 PHP或者使用PHP 7.0.22更高。這根本不可能。要麼更新您的PHP安裝或使用Symfony 3.4
