Rails:Module 的未定义方法“groups" [英] undefined method `groups' for Rails:Module

问题描述

像往常一样，我一直是个白痴，不知何故我的 mac 上的导轨坏了.我认为这一切都始于它说 rake 的版本不够新，所以我深入研究了不同 gem 等和不同版本 rails 的巨大道路，我最终从 github 获得了 rails，但它用最新的替换了它版本.

As usual I've been an idiot and broken rails on my mac somehow. I think it all started when it said the version of rake wasn't recent enough so I delved down a huge road of different gems etc. and different versions of rails, I ended up getting rails from github but it replaces it with the most recent version.

现在我担心我的所有配置文件都不正确，但是当我尝试 'rake rails:update' 时，我收到以下带有跟踪的错误:

Now I fear all of my configuration files are incorrect, but when I try to 'rake rails:update' I get the following error with a trace:

rake aborted!

今晚我已经受够了，我已经访问了 100 万条路由(这一切都始于尝试让身份验证添加工作).

I've pretty much had enough tonight, I've been down a million routes (it all started with trying to get an authentication add on to work).

我想要做的就是将配置文件重置为最初用于 rails 3.0.9 的配置文件，我的 gem 文件来自:

All i want to do is reset the config files to what they were originally for rails 3.0.9, my gem file went from:

gem 'rails', '3.0.9'

gem 'rails', '3.0.9'

到

gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'rails', :git => 'git://github.com/rails/rails.git'

回到

gem 'rails', '3.0.9'

gem 'rails', '3.0.9'

...我是个白痴...但是一个头疼得厉害的白痴.

...I'm an idiot...but an idiot with a huge headache.

推荐答案

我的错误:我有同样的错误，你可以在这里看到:

My error: I have the same error, as you can see here:

$ rails c production
config/application.rb:7: undefined method `groups' for Rails:Module (NoMethodError)
    from /usr/lib/ruby/gems/1.8/gems/railties-3.0.9/lib/rails/commands.rb:21:in `require'
    from /usr/lib/ruby/gems/1.8/gems/railties-3.0.9/lib/rails/commands.rb:21
    from script/rails:6:in `require'
    from script/rails:6

在 config/application.rb 文件中，我有以下几行:

In config/application.rb file, I have these lines:

if defined?(Bundler)
  Bundler.require(*Rails.groups(:assets => %w(development test)))
end

然后我检查了另一个 Rails 3 应用程序，在这个应用程序中我再次检查了这个文件，它包含以下几行:

Then I checked another Rails 3 app, in this app I checked again this file and it contains these lines:

Bundler.require(:default, Rails.env) if defined?(Bundler)

所以我替换了这条线，然后我开始工作了.

So I sustitute this line and I works.

我也希望成为您的解决方案.

I hope to be your solution too.
