Composer要求的PHP版本报错如何解决？

Question

我有一个在 Debian 11 服务器上使用 Yii2 框架制作的网站。

当我在我的服务器上执行composer update 时，它会在我的网络中返回以下错误：

Composer detected issues in your platform: Your Composer dependencies require a PHP version ">=8.0.0".

我不明白这个错误，因为我的服务器是 8.0.10 版

root@xxxx:/var/www/html/myweb# php -v
PHP 8.0.10 (cli) (built: Aug 25 2021 17:05:38) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.10, Copyright (c) Zend Technologies
    with Xdebug v3.0.4, Copyright (c) 2002-2021, by Derick Rethans
    with Zend OPcache v8.0.10, Copyright (c), by Zend Technologies

我已尝试使用以下命令：composer install --ignore-platform-reqs，它可以工作。 但是，我希望能够更正错误，并且作曲家更新也能正常工作。

如何修复php版本的composer错误？

Answer 1

您的作曲家似乎从不同的 php 版本运行。

您可以通过命令composer -vvv about查看您的composer php版本

尝试从不同的 php 运行 composer，例如：/path/to/bin/php /path/to/composer update。

如果可行，您可以为该命令设置别名。
