Question

我目前正在尝试将一个Mongo数据库与Devise一起运行。我正在使用Rails 3.2.2和Ruby 1.9.3，mongo_mapper 0.11.0，设计1.1.9和devise-mongo_mapper 0.0.2。我在网上提到了很多来源，但它们似乎总是过时的。

我现在面临的一个巨大问题涉及到devise-mongo_mapper。在终端上运行mongod时，尝试运行rails服务器会给我以下内容：

/usr/local/lib/ruby/gems/1.9.1/gems/devise-1.1.9/lib/devise.rb:193:in `mailer=': undefined method `ref' for ActiveSupport::Dependencies:Module (NoMethodError)
from /usr/local/lib/ruby/gems/1.9.1/gems/devise-1.1.9/lib/devise.rb:195:in `<module:Devise>'

from script/rails:6:in `require'
from script/rails:6:in `<main>'

我在网上查了一下，发现这可能是因为我的设计没有更新。试图更新它给了我这个：

Bundler could not find compatible versions for gem "devise":
  In Gemfile:
    devise-mongo_mapper (>= 0) ruby depends on
      devise (~> 1.1.0) ruby

    devise (2.0.4)

所以基本上，旧设备不起作用，最新版本与我当前的设计-mongo_mapper不兼容。有没有办法解决？无论是让所有这些程序一起工作的方法，还是一种不需要devise-mongo_mapper的方法都会很棒。

Answer 1

看看several of the forks。

他们只是碰撞了gemspec中的版本，代码可能没有改变。

Answer 2

您可以使用-v argument安装所需的任何宝石版本。

sudo gem install whatever -v 1.0.1

或者你可以看看Plastic Chicken建议的叉子。

Answer 3

我也遇到了同样的错误，运行“捆绑更新”解决了我的问题。

Rails，Devise和Mongo - 我使用哪些版本？
