我在为我的项目安装作曲家时遇到此错误。 这里是我的composer.json

我收到此错误：

1. 问题的树枝/扩展1.0.11

   • 安装请求 - >由树枝可满足/扩展[V1.0.1]。
   • avocode/form-extensions-bundle dev-master需要twig/extensions〜1.2 - >可以通过twig/extensions [1.4.x-dev]来满足。
   • 只能安装其中的一个：twig/extensions [v1.0.1，1.4.x-dev]。
   • avocode/form-extensions-bundle dev-master的安装请求 - >通过avocode/form-extensions-bundle [dev-master]可以满足。

Answer 1

您已经固定twig/extensions到1.0.1版本，但avocode/form-extension-bundle需要至少版本的扩展1.2工作。使用固定版本时，其他软件包不允许需要更高版本。

"require": 
    "twig/extensions": "1.0.1", 

为了解决依赖性冲突，你应该要求更高，非固定版本（即允许所有版本，但不包括v2.0）不是一个新的依赖的需求是这样的：

composer require 'twig/extensions:~1.2' 

另外，您可以删除与twig/extensions明确的相关性，因为它已经是你的新软件包的依赖，将用这个包起来，反正安装：

composer remove 'twig/extensions' 

然后安装您需要的软件包：

composer require 'avocode/form-extensions-bundle:dev-master'
