ruby-on-rails - 在rails5中使用rails_admin时出错

我正在尝试将rails_admin与rails5应用程序一起使用。 rails_admin 0.8.1无效，因为


Bundler找不到与宝石“ rails”兼容的版本：
快照（Gemfile.lock）：
导轨（= 5.0.0.beta1）

在Gemfile中：
导轨（ = 5.0.0.beta1）

rails_admin was resolved to 0.8.1, which depends on
  rails (~> 4.0)

然后我尝试通过使用github中的最新代码


gem'rails_admin'，git：'https://github.com/sferik/rails_admin.git'


现在，我对机架的依赖性越来越高。


在快照（Gemfile.lock）中：
机架（= 2.0.0.alpha）

在Gemfile中：
rails（ = 5.0.0.beta1）已解析为5.0.0.beta1，具体取决于
actionmailer（= 5.0.0.beta1）已解析为5.0.0.beta1，具体取决于
actionpack（= 5.0.0.beta1）已解析为5.0.0.beta1，具体取决于
机架（〜> 2.x）

rails_admin was resolved to 0.8.1, which depends on
  rack-pjax (~> 0.7) was resolved to 0.7.0, which depends on
    rack (~> 1.3)

rails (< 5.1, >= 5.0.0.beta1) was resolved to 5.0.0.beta1, which depends on
  sprockets-rails (>= 2.0.0) was resolved to 3.0.0, which depends on
    sprockets (>= 3.0.0) was resolved to 3.5.2, which depends on
      rack (< 3, > 1)

devise was resolved to 4.0.0.pre.dev, which depends on
  warden (~> 1.2.3) was resolved to 1.2.4, which depends on
    rack (>= 1.0)

devise was resolved to 4.0.0.pre.dev, which depends on
  warden (~> 1.2.3) was resolved to 1.2.4, which depends on
    rack (>= 1.0)

现在开始使用rails5还为时过早吗？我应该回到rails4.2吗？

最佳答案

我看到RA具有Rails5 gemfile https://github.com/sferik/rails_admin/blob/master/gemfiles/rails_5.0.gemfile。我会尝试升级到该文件中提到的所有宝石。
