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，所以我做了但是在安装它时仍然遇到了一些问题。如果有人知道它有什么问题，或者我需要别的东西，我希望得到你的帮助。感谢。

Answer 1

只需添加：

use Symfony\Component\Config\Resource\FileResource;

到src / Kernel.php的顶部，由于某种原因错过了。

之后，您可以继续composer install

Answer 2

请将composer create-project symfony/skeleton cost_management替换为composer create-project symfony/website-skeleton cost_management

            **OR**

您可以使用PHP7.2在Ubuntu上安装和设置Symfony4应用程序，这些步骤通过temminal执行：

composer create-project symfony/website-skeleton cost_management
cd cost_management
php -S 127.0.0.1:8000 -t public
ctrl + c退出服务器运行composer install
sudo chmod 777 -R var/cache/ var/log/
现在再次php -S 127.0.0.1:8000 -t public
现在，您可以通过此http://localhost:8000/检查您的浏览器，也可以直接访问http://localhost/project_directory/public/index.php

Note:- 1.默认情况下，symfony 4设置为dev环境，但您可以设置通过设置$_SERVER['APP_ENV']来设置您的环境 2.如果它正常工作，那么您将在底部看到404错误消息和分析器，因为它默认设置为dev模式。 3.按照文档Symfony 4 create your first page
