dreamhost与thumbs_up更新RubyGems版本依赖项问题

Question

我想在dreamhost上设置我的ror站点，但是，我正在使用需要ruby gems版本1.7.0及更高版本的gem（thumbs_up）。

目前的版本是：

terebellum]$ gem -v 
1.3.7 

我试图运行 “宝石更新--system”，我得到这个错误：

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. 

请指教。见下面的日志。

感谢

我会推荐给install RVM（因为Dreamhost wiki说，这是可以做到）和Ruby版本，你需要（比如说rvm install 1.8.7）。然后，如果您想更新Rubygems，则可以运行rvm rubygems 1.7.0（请参阅RubyGems CLI API）
