安装Administrate gem时出现问题，捆绑程序冲突

Question

我已经尝试了很多方法来让Administrate捆绑在一起，但我总是遇到问题，通常是围绕activesupport gem。它似乎在寻找两个相互冲突的版本，否则我完全读错了。

'bundle install‘之后的错误：

Bundler could not find compatible versions for gem "activesupport":
In Gemfile:
actionpack was resolved to 4.0.13, which depends on
  activesupport (= 4.0.13)

actionpack was resolved to 4.0.13, which depends on
  activesupport (= 4.0.13)

actionpack was resolved to 4.0.13, which depends on
  activesupport (= 4.0.13)

administrate was resolved to 0.0.2, which depends on
  rails (~> 4.2) was resolved to 4.2.0, which depends on
    activesupport (= 4.2.0)

administrate was resolved to 0.0.2, which depends on
  rails (~> 4.2) was resolved to 4.2.0, which depends on
    activesupport (= 4.2.0)

我已经尝试过'bundle update‘了。我在Ubuntu环境中工作，使用最新版本的ruby (2.4.0)

Answer 1

解决了它。将rails约束到4.2版并将gem i18n添加到Gemfile允许捆绑器完成
