推荐答案

我在一个新的 Rails 3.2.3 项目和 Gemfile 之后遇到了各种打包程序/gem 问题.我能够通过删除 Gemfile.lock 并重新运行捆绑安装"来克服它.附上我所做的日志，其中包括删除 ActiveRecord.希望这会有所帮助.

I had various bundler/gem problems with a fresh Rails 3.2.3 project followed by your Gemfile. I was able to get past it by removing Gemfile.lock and rerunning 'bundle install'. The log of what I did is attached and it includes excising ActiveRecord. Hope that this helps.
