我尝试了很多方法来安装它，我在他们的网站上看到了命令，所以我做到了，但安装时仍然遇到一些问题。 如果有人知道出了什么问题，或者我需要其他东西，我希望得到你的帮助。 谢谢。

请替换composer create-project symfony/skeleton cost_management与 composer create-project symfony/website-skeleton cost_management

            **OR**

您可以通过终端执行以下步骤在 Ubuntu 上使用 PHP7.2 安装和设置 Symfony4 应用程序:

1. composer create-project symfony/website-skeleton cost_management
2. cd cost_management
3. php -S 127.0.0.1:8000 -t public
4. ctrl + c退出服务器运行 composer install
5. sudo chmod 777 -R var/cache/ var/log/
6. 现在又来了php -S 127.0.0.1:8000 -t public
7. 现在您可以通过此 http://localhost:8000/ 检查您的浏览器或者直接访问，无需 http://localhost/project_directory/public/index.php 运行服务器

Note:- 1. 默认情况下 symfony 4 设置为开发环境，但您可以设置 通过设置 $_SERVER['APP_ENV'] 您的环境 2. 如果它工作正常，那么您将在底部看到 404 错误消息和探查器，因为它默认设置为 dev模式。 3. 要查看某些内容，您需要通过以下文档 Symfony 4 create your first page 创建您的第一个 Controller
