Laravel 5.6 + cPanel + Composer錯誤：即使安裝了7.2，也使用了錯誤的PHP

Question

我正在嘗試在cPanel沙箱上安裝Laravel 5.6，並且在安裝了7.2的情況下，作曲家嘗試使用PHP 5.6時，我得到了奇怪的行為。 詳細信息如下：

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

which php命令什么也不返回。 但是當我做alias我得到以下信息：

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

如果我運行php -v我會看到

# 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

我將假設它正在工作。 如您所知，我在cPanel上運行Laravel的經驗很少，但是我離題了。

這是錯誤：

# 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].

現在，我確實找到了一個線程，該線程說要向composer.json添加平台：

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

這確實讓我可以安裝我的供應商軟件包，但這顯然不是要作為解決方案，因為您只是在偽造該平台（我認為）。 當真正使用php7時，我在null合並運算符上收到以下錯誤，這是php 7的功能，因此它仍在嘗試使用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

補充筆記：

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"
}

關於如何解決此問題的任何想法？

Answer 1

在composer.json文件中提到的php版本是什么？ 確保它看起來像這樣

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

或者您可以嘗試以下解決方案之一：1）嘗試在服務器上重新安裝php 2）您可以忽略諸如composer install --ignore-platform-req這樣的依賴項

Answer 2

事實證明，解決方案最終是我們需要將默認的服務器范圍php版本更改為7.2，所以我們做到了。 由於我們擁有共享的托管設置，因此我們將所有以前的現有站點在本地默認設置為5.6，然后將所有Laravel安裝設置為7.2。 不知道這是否是最好的解決方案，但確實可以解決問題。
