【问题描述】：

我正在尝试在 cPanel 沙箱上安装 Laravel 5.6，并且在 composer 尝试使用 PHP 5.6 时出现了奇怪的行为，即使设置了 7.2。以下是详细信息：

# composer --version
Composer version 1.1.1 2016-05-17 12:25:44

命令which php 不返回任何内容。但是当我做alias 时，我得到以下信息：

alias php='/usr/local/bin/ea-php72'

如果我运行 php -v 我会看到

# php -v
PHP 7.2.4 (cli) (built: Apr  4 2018 00:56:46) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

我将假设它正在工作。如您所知，我在 cPanel 上运行 Laravel 的经验很少，但我离题了。

这是错误：

# composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - This package requires php ^7.1.3 but your PHP version (5.6.35) does not satisfy that requirement.
  Problem 2
    - laravel/framework v5.6.9 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.8 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.7 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.6 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.5 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.4 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.3 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.2 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.15 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.14 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.13 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.12 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.11 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.10 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.1 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.0 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework 5.6.x-dev requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - laravel/framework v5.6.15 requires php ^7.1.3 -> your PHP version (5.6.35) does not satisfy that requirement.
    - Installation request for laravel/framework 5.6.* -> satisfiable by laravel/framework[5.6.x-dev, v5.6.0, v5.6.1, v5.6.10, v5.6.11, v5.6.12, v5.6.13, v5.6.14, v5.6.15, v5.6.2, v5.6.3, v5.6.4, v5.6.5, v5.6.6, v5.6.7, v5.6.8, v5.6.9].

现在，我确实找到了一个线程，说要向 composer.json 添加一个平台：

"platform": {
    "php": "7.1.3"
}

这确实让我安装了我的供应商软件包，但它显然不是一个解决方案，因为你只是在伪造平台（我认为）。当真正使用 php7 时，我在 null 合并运算符上收到以下错误，这是 php 7 的一个功能，因此它仍在尝试使用 php5.6。

> Illuminate\Foundation\ComposerScripts::postAutoloadDump

Parse error: syntax error, unexpected '?' in /public_html/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php on line 233

补充说明：

phpinfo() - PHP Version 7.2.4
php.ini - /opt/cpanel/ea-php72/root/etc
core PHP Version 7.2.4

# /usr/bin/env php -v
ea-php-cli Copyright 2017 cPanel, Inc.
PHP 5.6.35 (cli) (built: Apr  4 2018 00:55:31)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

我需要的composer.json如下：

"require": {
    "php": "^7.1.3",
    "edujugon/laravel-google-ads": "^1.4",
    "fideloper/proxy": "^4.0",
    "laravel/framework": "5.6.*",
    "laravel/tinker": "^1.0"
}

关于如何解决此问题的任何想法？

标签： php cpanel php-5.6 laravel-5.6 php-7.2

【解决方案1】：

您在 composer.json 文件中提到的 php 版本是什么？确保它看起来像这样

 "require": {
        "php": "^7.1.3",
        "darkaonline/l5-swagger": "5.6.*",
        "fideloper/proxy": "^4.0",
        "laravel/framework": "5.6.*",
        "laravel/tinker": "^1.0"
    },

或者您可以尝试其中一种解决方案 1）尝试在您的服务器上重新安装php 2）你可以忽略这样的依赖 composer install --ignore-platform-reqs

【解决方案2】：

最终解决方案是我们需要将默认服务器范围的 php 版本更改为 7.2，因此我们这样做了。由于我们有一个共享主机设置，我们将所有以前的现有站点设置为本地默认为 5.6，并且以后任何 Laravel 安装都将设置为 7.2。不确定这是否是最好的解决方案，但它确实成功了。
