PHP-作曲家未能在symfony 4上要求symfony / symfony

我通过以下行通过composer安装了symfony的最新版本：

composer create-project symfony/skeleton whatever

然后,按照此page上的说明,我决定需要整个框架,因此不必通过输入以下命令逐个安装所有捆绑软件：

composer require symfony/symfony

但是问题是我最终遇到以下错误：

composer require symfony/symfony
Using version ^4.0 for symfony/symfony
./composer.json has been updated

当我指定版本4.0.2时,我少了2个错误,但问题仍然相同：

我的composer.json：

            "allow-contrib": false
        }
    }
}

我很困惑,我无法在symfony doc上找到很多有关此的信息,而且我与作曲家相距甚远,有什么线索吗？

解决方法:

symfony / skeleton软件包设计用于Symfony Flex.该项目的重点是避免使用整个框架,因此该软件包与之明显冲突.

您应该从symfony / framework-standard-edition创建项目,该项目将引入整个框架,或者利用Flex中的新功能仅引入所需的组件或“recipes”.
