Question

'捆绑更新'给了我一些非常奇怪的错误。 arel，activemodel和rack列在下面，因为没有兼容的版本。每个都列出两次，具有相互矛盾的版本要求：

$ bundle update
Updating https://github.com/bborn/communityengine.git
Updating https://github.com/bborn/authlogic.git
Updating https://github.com/paneq/calendar_date_select.git
Fetching source index for http://rubygems.org/
Bundler could not find compatible versions for gem "arel":
  In Gemfile:
    community_engine (= 2.0.0.beta) depends on
      arel (~> 2.1.1)

    community_engine (= 2.0.0.beta) depends on
      arel (2.2.1)

Bundler could not find compatible versions for gem "activemodel":
  In Gemfile:
    community_engine (= 2.0.0.beta) depends on
      activemodel (= 3.1.0.beta1)

    community_engine (= 2.0.0.beta) depends on
      activemodel (3.1.0.rc2)

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    community_engine (= 2.0.0.beta) depends on
      rack (= 1.3.2)

    community_engine (= 2.0.0.beta) depends on
      rack (1.3.3)

gem list显示已安装合适的版本：

rack (1.3.3, 1.3.2)
arel (2.2.1, 2.1.1)
activemodel (3.1.0, 3.1.0.rc2, 3.1.0.beta1)

它变得更加奇怪。将我的Gemfile中的3个额外的gem行从末尾移动到中间（在'source'和'gem rails'行之后）改变了bundle报告的错误：

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    rails (= 3.1.0) depends on
      actionpack (= 3.1.0)

    community_engine (= 2.0.0.beta) depends on
      actionpack (3.1.0.rc2)

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    community_engine (= 2.0.0.beta) depends on
      rack (= 1.3.2)

    community_engine (= 2.0.0.beta) depends on
      rack (1.3.3)

社区发动机的宝石在这里肯定是可疑的，我也在他们的论坛上寻求答案。但捆绑者的这种奇怪错误要求更广泛的受众。

任何建议，伙计们？ THX！

FWIW，在community_engine的README.markdown（https://github.com/bborn/communityengine/blob/master/README.markdown）上，它说：

要求：


RAILS VERSION 2.3.4（尚不支持更高版本）

但看起来你正试图使用Rails 3.1？

“捆绑更新”报告没有兼容版本的宝石，版本要求相互矛盾
