我正在努力让自己继续从事开源项目：KiungoWiki
几个月前，我可以简单地启动数据库
mongod
启动服务器
$ rails s
并转到 localhost:3000 以查看一切正常运行。
现在，由于某种原因，情况发生了变化。我仍然可以启动数据库：
$ mongod
mongod --help for help and startup options

但是当我尝试启动服务器时，会发生奇怪的事情：

Could not find tilt-1.3.3 in any of the sources
Run `bundle install` to install missing gems.
我已经尝试了错误消息提示的所有方法，但均无济于事。现在，我想开始了解问题的真正含义。有什么帮助吗？
顺便说一句：我正在尝试使用来自 github 的最新代码，它非常适合项目中的其他开发人员。
更新 我尝试运行
gem update --system
但得到以下结果：

ERROR: gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories.
If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian.
甚至gem --version吐出错误

1.7.2
更新问题已更改
按照@Andreas 的建议，我删除了我的 gem 文件夹并重新安装了所有内容
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )
rvm requirements
rvm reload
gedit .bashrc &
rvm reinstall 1.9.2
rvm gemset create rails3
rvm 1.9.2@rails3 gem update --system
rvm 1.9.2@rails3 gem install rails --version 3.1.1
cd Documents/Projets/KiungoWiki
bundle install
没有任何错误。mongod工作正常，但rails s说：
=> Booting WEBrick
=> Rails 3.1.1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
