无法在Rails 4.0.0.rc1中检测association_proxy.rb

Question

我在composite_primary_keysRails 4.0.0.rc1中使用gem.添加到Gemfile后

gem 'composite_primary_keys'

并添加了运行bundle install

require 'composite_primary_keys'

到application.rb.但是,当我运行时rails generate create_table,我收到以下错误:

  /Users/name/.rvm/gems/ruby-1.9.3-p385/gems/activesupport-4.0.0.rc1/lib/active_support/dependencies.rb:228:in `require':

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

我检查composite_primary_keys.rb了这个gem中的文件,发现它是必需的association_proxy.rb.但是,似乎Rails无法找到此文件.

我是否在错误的时间需要这个宝石与Rails装载订单？或者这是因为association_proxy.rb不再在Rails 4中？

与使用的差异有同样的问题

gem 'composite_primary_keys', '=3.1.0'

通过刮擦版本并运行来修复它

bundle update composite_primary_keys

尝试不同的版本可能有所帮助.
