Ruby on rails Rails:尝试安装gem时出现错误消息

我正在尝试安装一个很棒的Ruby gem，名为Forem，它给了我一个WillPaginate模块的错误。我假设Forem使用的工具将对gem进行分页，即使我在gem文件中没有看到它

这个Forem gem是一个论坛应用程序，通常对我有效，但这次我将它与另一个伟大的gem Enki结合，用于博客，也使用will_paginate。Enki通常运行在3.0应用程序上，但我经历了3.1更新，所以至少在这方面，它应该与Forem兼容，Forem也是3.1应用程序

这是我尝试使用此命令安装Forem时收到的错误消息

 rails g forem:install

有人知道我该怎么解决这个问题吗

错误

你能发布config/initializers/will_paginate.rb的内容吗？使用的是什么版本的will_paginate？3.0最终版本更改了Enki博客中的一些方法名称，我首先安装了它，它使用gem'will_paginate'，'=3.0.pre2'，但我甚至无法在Forem gem中看到will_paginate，这会导致错误，即使Forem没有将其列为依赖项，如果定义了WillPaginate，它仍将运行该初始值设定项。您能将WillPaginate更新到v3.0.3吗？似乎每个页面都是在中定义的。这修复了它。如果你写一个答案，我会接受的。谢谢
