Laravel 无法使用Laradock为SSR安装v8js扩展

我正在尝试使用需要的管理服务器端渲染。我的工作环境是

我已在Laradock.env文件中启用V8JS安装：

WORKSPACE_INSTALL_V8JS=true

我通过docker compose重建了我的工作区和php fpm图像

docker-compose build workspace php-fpm
docker-compose restart

当我试图在容器中安装react-laravel时，我遇到这样的错误：

Problem 1
 - reactjs/react-php-v8js dev-master requires ext-v8js >=0.1.3 -> the requested PHP extension v8js is missing from your system.
    - talyssonoc/react-laravel v0.11 requires reactjs/react-php-v8js dev-master -> satisfiable by reactjs/react-php-v8js[dev-master].
    - Installation request for talyssonoc/react-laravel 0.11 -> satisfiable by talyssonoc/react-laravel[v0.11].

我几乎损失了一整天，我对解决这个问题失去了希望。 你知道怎么回事吗

这就是运行php fpm容器所产生的结果
