Rails的未定义方法`groups':模块

Question

像往常一样,我以某种方式在我的Mac上一直是个白痴和破坏的铁轨.我认为这一切都是在它说rake的版本不够新的时候开始的,所以我深入研究了不同宝石的巨大道路等等和不同版本的rails,我最终从github获得了rails,但它取代了最近的版.

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,我得到以下错误跟踪:

rake aborted!
undefined method `groups' for Rails:Module
/Users/jamielawrence/Documents/Websites/JaphexPortfolio/config/application.rb:8
/Library/Ruby/Site/1.8/rubygems/custom_require.rb:36:in `gem_original_require'
/Library/Ruby/Site/1.8/rubygems/custom_require.rb:36:in `require'

/Library/Ruby/Gems/1.8/gems/rake-0.9.2/bin/rake:32
/usr/bin/rake:19:in `load'
/usr/bin/rake:19

今晚我已经足够了,我已经减少了一百万条路线(这一切都始于试图获得认证加入工作).

我想要做的就是将配置文件重置为原来的rails 3.0.9,我的gem文件来自:

宝石'轨道','3.0.9'

至

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

回到

宝石'轨道','3.0.9'

......我是个白痴......但是一个头疼的白痴.

我的错误:我有同样的错误,你可以在这里看到:

$ 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,我有这些行:

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,它包含以下行:

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

所以我替换这一行并且我工作.

我希望也成为你的解决方案.

阅读这篇文章：http://ryan.mcgeary.org/2011/02/09/vendor-everything-still-applies/

或者

TLDR bundle install --path vendor然后bundle --binstub然后bin/rake whatever

哦，不要忘记应用程序目录中的 .rvmrc
