Jruby：无法在 rails 应用程序的 jruby 中启动 webrick 服务器

Question

我已经在我的 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，我想运行使用 webbrick 服务器，但我无法运行它。每当我使用命令 rails 启动 webrick 服务器时，我都会遇到以下错误。

在 Jruby 应用程序中启动服务器

谢谢，

Answer 1

Bundler 1.13.1 有一个问题导致了这个 - 基本上他们移植了 require 方法，而在 JRuby 1.7 中，一个可见性错误因此使 Kernel::require 私有。

3 件事你可以做：

将 Kernel.require 可见性更改为 public（加载 Bundler 后）
降级到 Bundler 1.12
升级到 JRuby 1.7.26（尚未发布）
