rails/中间商依赖关系需要不同版本的宝石。

Question

我试图将middleman-cloudfront gem添加到我的中间人项目中，但得到了以下错误。大多数gem需要>= 4.0版本的middleman-core gem，但是middleman-cloudfront需要~> 3.0版本。

我怎样才能解决这个问题？

Bundler could not find compatible versions for gem "middleman-core":

In Gemfile:
middleman (>= 4.0.0) was resolved to 4.0.0, which depends on
  middleman-core (= 4.0.0)

middleman-cloudfront (~> 0.2.1) was resolved to 0.2.1, which depends on
  middleman-core (~> 3.0)

middleman-google-analytics (>= 2.1.1, ~> 2.1) was resolved to 2.1.1, which depends on
  middleman-core (>= 3.4)

middleman-s3_sync (>= 4.0.3, ~> 4.0) was resolved to 4.0.3, which depends on
  middleman-core (>= 4.0.0)

middleman-s3_sync (>= 4.0.3, ~> 4.0) was resolved to 4.0.3, which depends on
  middleman-core (>= 4.0.0)

middleman-sprockets (~> 4.0) was resolved to 4.0.0, which depends on
  middleman-core (~> 4.0)

它看起来像对v4的支持已经添加到中间人-云阵线，但还没有作为一个新版本发布。你可以直接从师父那里拉：

gem 'middleman-cloudfront', github: 'andrusha/middleman-cloudfront'
