Question

我在我的ubuntu机器上安装了jruby 1.7.16和rails 4.1.8。我有现有的jruby应用程序，我想使用webbrick服务器运行，但我无法运行它。每当我使用命令轨道启动webrick服务器时，我都会收到以下错误。

以下是我的jruby版本信息

jruby -v
jruby 1.7.16 (1.9.3p392) 2014-09-25 575b395 on Java HotSpot(TM) 64-Bit Server VM 1.8.0_101-b13 +jit [linux-amd64]

我的rails版本是4.1.8。请帮我在带有rails的Jruby应用程序中启动服务器。

谢谢，

Bundler 1.13.1存在导致这种情况的问题 - 基本上他们移植了require方法，而在JRuby 1.7中，可见性错误因此使Kernel::require变为私有。

你可以做的3件事：

将Kernel.require可见性更改为公开（在加载Bundler之后）
降级至Bundler 1.12
升级到JRuby 1.7.26（尚未发布）

Jruby：无法在jruby on rails应用程序
