我正在开发一个Rails 2.3.8项目。我已将项目克隆到我的服务器但无法启动应用程序。以下是我得到的错误。我听说你可以安装Bundler for 2.3.8，这可能会解决问题，但我想知道我是否只是遗漏了一些东西。关注gem 作为本地gem安装。
非常感谢你的帮助。

你正在使用太新的回形针 - 你需要确保它的v2.7，而不是堆栈跟踪中的3.0：
来自/home/ankasa/ruby/gems/gems/paperclip-3.0.0/rails/init.rb:1:in`valuation_init_rb'回形针自述文件中有更多内容，但Paperclip 3.0中基本上删除了Rails 2.3支持
