用于我们的redmine-installation（=＆gt;项目计划，票务等工具） 我们在服务器上安装了ruby，工作得很好...... 但是现在我们需要一个rails更新（Rails 3.2.3）来进行redmine更新 所以麻烦开始了：
我做了以下事情：
1。）安装ruby 1.9.3
root@information:~# rvm install 1.9.3
Installing Ruby from source to: /usr/local/rvm/rubies/ruby-1.9.3-p194, this may take a while depending on your cpu(s)...

Depending on your version of ruby, you may need to install ruby rdoc/ri data:
<= 1.8.6 : unsupported
= 1.8.7 : gem install rdoc-data; rdoc-data --install
= 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!

我的问题是，redmine 2.0.1与ruby 1.9.3有问题 因此试图通过例如降级红宝石“rvm uninstall 1.9.3”并尝试过 重新安装ruby 1.8.6 ......
毕竟我刚刚升级到ruby 1.9.3但未能升级到rails 3.2.5 ....
你能在这帮我吗？我是红宝石的新手。我忘了安装步骤了吗？ 在此先感谢您的帮助？ 欢呼声，
安斯加尔
