作曲家没有要求symfony/symfony在symfony 4上

Question

我已经通过composer安装了symfony的最后一个版本，行如下：

composer create-project symfony/skeleton whatever

然后，按照这个页面上的说明，我决定需要整个框架，所以不必一个接一个地安装所有的包，只需输入以下内容：

composer require symfony/symfony

但问题是，我最终犯了以下错误：

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 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，我少了两个错误，但问题仍然是一样的：

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

Updating dependencies (including require-dev)

我的composer.json：

            "allow-contrib": false
        }
    }
}

我很困惑，我在symfony医生上找不到很多关于这方面的信息，而且我对作曲家也不太在行，有什么线索吗？

Answer 1

symfony/skeleton包被设计为与Symfony Flex一起使用。该项目的全部目的是避免使用整个框架，因此包明确地与其冲突。

您应该从symfony/framework-standard-edition创建项目，这将引入整个框架，或者使用Flex中的新功能来导入所需的组件或“食谱”。
