当我尝试使用jRuby启动我的Rails应用程序时,它说我需要安装已经安装的rails 2.3.8。这些是我使用的命令及其错误:
尝试启动应用程序:
[root @ node app]#/ opt / jruby-1.5.2 / bin / jruby -S /opt/jruby-1.5.2/bin/glassfish -p 3001
在开发环境中启动GlassFish服务器:0.0.0.0:3001 ...
将日志消息写入:/opt/app/log/development.log 按Ctrl + C停止。缺少Rails 2.3.8 gem。请
gem install -v=2.3.8 rails
,更新您已安装的Rails版本的config / environment.rb中的RAILS_GEM_VERSION设置,或注释掉RAILS_GEM_VERSION以使用安装的最新版本。
本地宝石:
[root @ node app]#/ opt / jruby-1.5.2 / bin / jruby -S gem list

我遇到了完全相同的问题,最后通过卸载Rack版本解决了这个问题,因此只剩下一个Rack版本。
我实际上仍然想知道如何导致此错误。
