在我执行时php -v,它说它有php7

但是当我尝试执行时 composer update

它的回应

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

  Problem 1
    - This package requires php >=7.0.0 but your PHP version (5.6.33) does not satisfy that requirement.

我怎样才能解决这个问题？注意:我不允许卸载以前版本的php

这是composer.json

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=7.0.0",
        "fideloper/proxy": "~3.3",
        "intervention/image": "^2.4",
        "laravel/framework": "5.5.*",
        "laravel/passport": "^v1",
        "laravel/tinker": "~1.0"
    },
    "require-dev": {
        "filp/whoops": "~2.0",
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~6.0"
    }, …

这是我打开网站时的实际错误

实际上，我已经成功运行php artisan migrate:refresh，并且没有错误。

已经尝试了以下命令。

php artisan cache:clear
php artisan config:clear

composer install
composer clearcache
composer dump-autoload
php artisan clear-compiled

我还检查了pdo是否已安装，是否php -m已经安装

我正在使用CentOS。
