我已经通过 composer 安装了最新版本的 symfony，代码如下：

composer create-project symfony/skeleton whatever

然后按照此页面上的说明，我决定需要整个框架，因此我不必通过输入以下内容一一安装所有捆绑包：

composer require symfony/symfony

但问题是我最终出现以下错误：

composer require symfony/symfony
Using version ^4.0 for symfony/symfony
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - symfony/symfony v4.0.0 conflicts with __root__[No version set (parsed as 1.0.0)].
    - symfony/symfony v4.0.1 conflicts with __root__[No version set (parsed as 1.0.0)].
    - symfony/symfony v4.0.2 conflicts with __root__[No version set (parsed as 1.0.0)].
    - Installation request for __root__ No version set (parsed as 1.0.0) -> satisfiable by __root__[No version set (parsed as 1.0.0)].
    - Installation request for symfony/symfony ^4.0 -> satisfiable by symfony/symfony[v4.0.0, v4.0.1, v4.0.2].


Installation failed, reverting ./composer.json to its original content.

当我指定版本4.0.2时，我少了 2 个错误，但问题仍然存在：

composer require symfony/symfony v4.0.2
./composer.json has been updated

我的作曲家.json：

            "allow-contrib": false
        }
    }
}

我很困惑，我在 symfony 文档上找不到太多关于这个的信息，而且我对作曲家还很陌生，有什么线索吗？

该symfony/skeleton软件包旨在与Symfony Flex一起使用。该项目的全部目的是避免使用整个框架，因此包明确与它冲突。

您应该从 中创建您的项目symfony/framework-standard-edition，这将拉入整个框架，或者利用 Flex 中的新功能来拉入您需要的组件或“配方”。
