由于php版本问题，无法使用composer建立laravel项目

Question

我使用的是具有多个我自己的域的共享主机。我买了一个新的，并且专门要求我使用 php 8.2 或更高版本。使用 MultiPHP 管理器，我将其设置为 PHP 8.2 (ea-php82) 并在域目录中运行 php -v 命令，它说：

PHP 8.2.18 (cli) (built: Apr 18 2024 09:00:42) (NTS)

Copyright (c) The PHP Group

Zend Engine v4.2.18, Copyright (c) Zend Technologies

现在，当我运行composer命令composer install时，我收到一堆错误，说我正在使用8.1所以我输入了这些命令：

[foo@foo foo.com]$ which php
/usr/local/bin/php
[foo@foo foo.com]$ /usr/local/bin/php -v
PHP 8.2.18 (cli) (built: Apr 18 2024 09:00:42) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.18, Copyright (c) Zend Technologies
[foo@foo foo.com]$ which composer
/opt/cpanel/composer/bin/composer

然后根据需要输入此命令，就会发生这种情况：

[foo@foo foo.com]$ /usr/local/bin/php /opt/cpanel/composer/bin/composer install
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Your lock file does not contain a compatible set of packages. Please run composer update.

  Problem 1
    - Root composer.json requires php ^8.2 but your php version (8.1.28) does not satisfy that requirement.
  Problem 2
    - laravel/framework is locked to version v11.4.0 and an update of this package was not requested.
    - laravel/framework v11.4.0 requires php ^8.2 -> your php version (8.1.28) does not satisfy that requirement.
  Problem 3

现在，如果我尝试的最后可能的事情是使用忽略平台要求，这也导致了错误：

[foo@foo foo.com]$ /usr/local/bin/php /opt/cpanel/composer/bin/composer install --ignore-platform-reqs
Installing dependencies from lock file (including require-dev)

有什么解决办法吗？

我尝试在 cPanel 中使用 MultiPHP 管理器。我尝试过给出不同的 php 版本路径。我也尝试过使用作曲家的忽略平台要求命令。

Answer 1

更新你的composer.json

"require": {
    "php": "^8.18",
