【问题描述】：
我正在尝试在 dreamhost 上设置我的 ror 站点，但是，我使用的 gem (thumbs_up) 需要 ruby gems 版本 1.7.0 及更高版本。
当前版本是：
terebellum]$ gem -v
1.3.7
我尝试运行“gem update --system”并收到此错误：
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。请参阅下面的日志。
谢谢
