#39 楼 @rei 应用成功启动了。 [*****@v125010146 wtn]$ sh restart.sh Starting server on 0.0.0.0:8080 ... Starting server on 0.0.0.0:8081 ... Starting server on 0.0.0.0:8082 ... Starting server on 0.0.0.0:8083 ... Starting server on 0.0.0.0:8084 ...

应该是可以。

谢谢你！真的，我不知道该如何表达我的感谢

#39 楼 @rei 哈哈，我发誓我再也不在生产环境玩了

#33 楼 @rei warning 没了，但还是报这个错误，我感到挺沮丧，你确实在帮我。似乎这个问题比我们想象的更难解决

bundle install 似乎成功了

gem uninstall xxx 正常情况下会给出一些信息反馈的么？比如成功了或失败了

#10 楼 @rei 这是我再 stack 上提的问题，也有人回复了，http://stackoverflow.com/questions/30682575/rails-v-got-error-already-initialized-constant

#8 楼 @rei 在删除 rvm 前就报这个错误了，删除 rvm 是在尝试重启应用失败后的操作，因为我觉得有 rvm 安装了 ruby 2.0.0-p643，系统默认也有一个 ruby 2.0.0-p247 可能会有冲突。但是删除 rvm 之后，仍然报告相同的错误

$ ruby -v ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux] #8 楼 @rei

我换另一种方式尝试启动：

#3 楼 @rei 维护者刚移交到我这，因为一直都是可以启动的。

最近我再这台机器上做了这些事情，可能导致了这个问题出现 安装 rvm， rvm install ruby 2.2 rvm install ruby 2.0

部署了另一个 rails 项目，但并没有启动它

删除了 rvm

#1 楼 @rei 我对 ruby 不是很熟，只是在维护公司的 redmine，现在这个应用起不起来了，挺着急的。 我觉得

(eval):9: warning: already initialized constant Bundler::Dsl::RAILS_VERSION_IS_3

这个错误提示很关键，似乎有另一个 rails 实例，但是不清楚如何处理，希望可以获得帮助？

#1 楼 @rei 能提供一些建议或者帮助么 -。-

#105 楼 @vincenttone 说的真好，这才是社区的精神！
