每当我运行 artisan 命令时，我都会遇到这个问题。
我正在使用 Valet 和 PHP 8.1。我已尝试更改 PHP 版本，但仍然遇到此问题。
当我跑步时：
jakefeeley@Jakes-MBP marketing % php artisan plugin:install vojtasvoboda.twigextensions

根据我的经验，这是由于尝试在 PHP 8.1 下运行 Laravel 7（或更早版本）造成的。我知道您说过您尝试更改 PHP 版本，但我会仔细检查您的更改是否确实生效。
对于 Laravel 7，切换回 PHP 8.0 解决了我的问题。
nb：Laravel 7 的
composer.json"php": "^7.2.5|^8.0",就我而言，我有 Laravel 8.12，然后我收到了这个错误。 所以我在 Composer.json 中将
"laravel/framework": "^8.12","laravel/framework": "^8.75",composer update*最后，当我运行时
php artisan --version我运行了作曲家更新，它修复了问题
当我将 php 版本从 7 更新到 8 时，我遇到了同样的问题。 我将“laravel/framework”更新为“^8.75”并运行作曲家更新。这对我有用。
当我尝试在 php 8.1 上运行 Laravel 7.3 时，我遇到了同样的错误
对我来说，我的电脑上安装了 2 个版本的 php，
php-7.4 and php-8.1.当我在终端上检查 php 版本时，使用
php --version所以我以为 Laravel 使用的是 php 7.4，但事实并非如此。不知何故，Web 服务器（nginx）重定向到 php 8.1
要确定正在使用哪个 php 版本，请使用内置的 phpinfo() 方法。以下是一种方法
在index.php文件中添加以下内容
<?php
phpinfo();
?>
然后尝试访问您的 Laravel 项目。 这将为您提供 php 信息页面，其中包含有关您的 Laravel 项目实际使用的 php 版本的信息。
当我在 macOS Big Sur 上使用自制程序时，我使用这些命令来停止 php8.1
brew services stop [email protected]
brew unlink [email protected]
然后我开始了 php 7.4
brew services start [email protected]
brew link [email protected]
由于 laravel/php 版本，我遇到了同样的问题，我使用的是 laravel 6.X LTS 和 php 8.1，它们不兼容，您可以在此处查看https://laravel.com/docs/9.x/releases 所以你有两个选择，要么升级你的 laravel 要么降级你的 php，我的例子是我使用 Homestead 和 Vagrant，所以在你的 Homestead.yaml 的
sitessites:
- map: your-site.local
to: /home/vagrant/your-site/public
php: "7.4"
或者您想要使用并运行的任何 php 版本
vagrant reload --provision我在使用 homestead 运行我的网络应用程序（使用 laravel 和 php7.3 ）时遇到此错误。我花了很长时间才终于发现我得到的错误是在主机中运行 php8 导致的。
所以我也将主机上的php版本更改为7.3。
现在问题全部消失了。
我不知道为什么，但显然，主机中的 php 确实也会影响 homesteead 中的 php。
所以你需要确保homestead中的php版本与宿主机相同。
尝试检查composer.json和package.json的依赖关系，检查所有依赖关系是否都在正确的位置（对于生产->依赖关系而不是依赖关系-开发）
