这是我的Gemfile：

应用程序在Puma服务器上成功运行(在添加warbler之前).

我刚刚安装了warbler

宝石安装鸣鸟

然后我跑了起来.但是我得到了错误：

LoadError: no such file to load -- zip/zip
  require at org/jruby/RubyKernel.java:1054

     eval at org/jruby/RubyKernel.java:1093
   (root) at /home/stever/.rvm/gems/jruby-1.7.4/bin/ruby_noexec_wrapper:14

然后我尝试将其添加到Gemfile中,如上所述.即使这样我也会收到错误.我现在也无法启动我的Puma服务器.

我确实安装了rubyzip.
