Warbler - 没有这样的文件来加载错误

Question

我按照此处的指南将Redmine安装到Tomcat，但我正在运行运行 Warbler 时遇到问题。当我尝试运行时，

ruby /var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble config

出现此错误，

/var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble:10:in `require': no such file to load -- warbler (LoadError) 
from /var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble:10

我四处搜索，发现这是由于不需要 ruby​​gems 引起的。当我尝试修复此问题并运行时，

ruby -rubygems /var/lib/gems/1.8/gems/warbler-1.2.1/bin/warble config

我现在遇到此错误

warble aborted!
no such file to load -- /var/lib/gems/1.8/gems/jruby-rack-1.0.5/lib/jruby-rack-1.0.5.jar
/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'

当我使用 --trace 运行最后一个命令时，我得到此

warble aborted!

文件 /var/lib/gems/1.8/gems/jruby-rack-1.0.5 /lib/jruby-rack-1.0.5.jar 存在，所以我不确定为什么它会遇到问题。

这是 gem list 的输出，以防万一它有用。

Answer 1

一种临时解决方案是使用旧版本的 jruby-rack：

gem uninstall jruby-rack

如果删除此 gem，将无法满足一个或多个依赖项。
继续卸载吗？ [Yn]

类型 Y

gem install jruby-rack -v 1.0.3

Answer 2

或者只是使用

gem install jruby-rack --pre

并在 Gemfile 中设置

gem 'jruby-rack', '~> 1.0.6.beta'
