Composer無法在symfony 4上要求symfony / symfony

Question

我已經通過composer安裝了最新版本的symfony，其中包含以下行：

composer create-project symfony/skeleton whatever

然后按照本頁面上的說明，我決定要求整個框架，所以我不能通過輸入以下內容逐個安裝所有捆綁包：

composer require symfony/symfony

但問題是我最終得到以下錯誤：

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.

當我指定版本4.0.2我有2個錯誤少，但問題保持不變：

composer require symfony/symfony v4.0.2
./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 v4.0.2 conflicts with __root__[No version set (parsed as 1.0.0)].
    - Installation request for symfony/symfony v4.0.2 -> satisfiable by symfony/symfony[v4.0.2].

我的composer.json：

        "post-install-cmd": [

            "allow-contrib": false
        }
    }
}

我很困惑，我在symfony doc上找不到關於這個的很多信息，而且我對作曲家，任何線索都不是很好？

Answer 1

symfony/skeleton包旨在與Symfony Flex一起使用。 該項目的重點是避免使用整個框架，因此包與它明確沖突。

您應該從symfony/framework-standard-edition創建項目，這將引入整個框架，或者利用Flex中的新功能來提供您需要的組件或“配方” 。
