有没有一种快速方法将一个jruby on rails应用程序打包到一个罐子里？

在轨道应用程序上的jruby虚拟设备上是否有ec2？

如果可能的话,我宁愿不使用javascript,但jquery解决方案也可以.我很感激任何帮助.

日期对象实例化如下:

new Date("2011-12-13")

返回一个认为自己是星期一的日期对象:

Date {Mon Dec 12 2011 16:00:00 GMT-0800 (PST)}

但根据我的日历,12/13/2011是星期二.奇怪的是,当我像这样实例化日期对象时:

new Date("12/13/2011")

这(正确)返回星期二:

Date {Tue Dec 13 2011 00:00:00 GMT-0800 (PST)}

如何在我的初始示例(年 - 月 - 日)中使用语法,并根据我的日历获取一周中的正确日期？

我试图弄清楚为一个应用程序编写了多少行代码。代码位于当前目录和子目录中。我正在使用 ubuntu。

当我尝试启动rails服务器时,rails s我收到此错误:
