将 Symfony 2.6 更新到 2.7

Question

>im 试图将 symfony 2.6 更新到 2.7

我已经在我的作曲家.json中更改为2.7版本

"symfony/symfony": "2.7.*"

IM 正在运行

composer update symfony/symfony --with-dependencies

并收到此错误

    - Installation request for symfony/asset (locked at v3.4.4) -> satisfiable by symfony/asset[v3.4.4].

我不明白它想从我这里得到什么

这是我的作曲家.json

    }
}

我已经单独更新了symfony/资产，但它没有帮助还尝试更新sensio/framework-extra-bundle和vich/uploader-bundle引用 symfoy/asset bundle这也无济于事

Answer 1

感谢您的评论

我已经安装了干净的Symfony 2.7

基于以前的composer why symfony/asset
这告诉我vich/uploader-bundle 1.4.2 requires symfony/asset (^2.3|^3.0)

我首先添加了它composer require vich/uploader-bundle它自动添加了版本 ^0.14.0

我已将其复制到我的作曲家并仅更新了它 composer update vich/uploader-bundle --with-dependencies

之后将Symfony版本更改为2.7并更新 composer update symfony/symfony --with-dependencies

一切都很好:)
