从 rails 3.1 升级到 3.2.6 后出错

Question

我为自己设定了在本地 mac book air lion 开发环境中将我的应用程序从 rails 3.1 升级到 rails 3.2.6 的任务。我关注了guide 并升级了 ruby​​，我的所有 gem 似乎都已安装，并且 rails -v 给出了 rails 3.2.6 的答案。如果我运行任何 rails 命令，例如rails c 启动控制台，我明白了：

MacBook-Air:myapp bob$ rails c
/Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/pubnub-ruby-0.0.9/lib/pubnub-ruby.rb:1:in `require': cannot load such file -- ./pubnub.rb (LoadError)
    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/pubnub-ruby-0.0.9/lib/pubnub-ruby.rb:1:in `<top (required)>'
    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/bundler-1.0.21/lib/bundler/runtime.rb:68:in `require'

    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/bundler-1.0.21/lib/bundler/runtime.rb:66:in `each'
    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/bundler-1.0.21/lib/bundler/runtime.rb:66:in `block in require'

    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/bundler-1.0.21/lib/bundler/runtime.rb:55:in `require'
    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/bundler-1.0.21/lib/bundler.rb:122:in `require'
    from /Users/bob/work/myapp/config/application.rb:13:in `<top (required)>'
    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/railties-3.2.6/lib/rails/commands.rb:39:in `require'
    from /Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/railties-3.2.6/lib/rails/commands.rb:39:in `<top (required)>'
    from script/rails:6:in `require'
    from script/rails:6:in `<main>'

是的，我确实在我的应用程序中使用了 pubnub - 它一直运行良好，所以我不怀疑这一定是问题所在。

application.rb 第 13 行（可能不相关）是

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  Bundler.require *Rails.groups(:assets => %w(development test))
  # If you want your assets lazily compiled in production, use this line
  # Bundler.require(:default, :assets, Rails.env)
end

我会在部署之前预编译资产。

/Users/bob/.rvm/gems/ruby-1.9.3-p0@rails32/gems/pubnub-ruby-0.0.9/lib/pubnub-ruby.rb:1 文件存在，我打开了它很好。

有谁知道发生了什么/是 pubnub 特定的还是其他的？我不确定如何进一步排除故障，到目前为止，谷歌搜索还没有发现任何问题。

谢谢，

戴夫

我在repo for that gem 中看不到文件pubnub-ruby.rb。尝试运行$ bundle install 或$ gem update pubnub-ruby。
