tomcat - 莺 - 没有这样的文件加载错误

Question

我正在按照位于 here 的指南进行操作将 Redmine 安装到 Tomcat，但我在运行 Warbler 时遇到了问题。当我尝试运行时

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

我收到这个错误

/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rubygems造成的。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

我现在遇到了这个错误

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，我得到了这个

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会遇到问题。

这是 gem list 的输出，以防万一它有用。

Answer 1

临时解决方案是使用旧版本的 jruby-rack:

gem 卸载 jruby-rack

如果您删除此 gem，将无法满足一个或多个依赖项。
继续卸载？ [Yn]

输入Y

gem install jruby-rack -v 1.0.3
