在通过rvm安装Ruby 1.9.3时出现错误。

在此之前，我成功安装了新的ruby版本。 我发现在谷歌这样的错误，但没有这个问题的答案。 和rails服务器无法启动。
我不得不升级RVM。
rvm get head rvm reload rvm install 1.9.3-p194 rvm use 1.9.3
如果1.9.3-p194不是最新的版本（截至2012年7月6日），请到Ruby网站查看是什么。
我不明白为什么使用gem update --system更新到RubyGems 1.8.11之后，同样的安装程序错误触及了我，它仍然在$RVM_HOME/src/rubygems-1.6.2/
更新1：我没有尝试rvm get latest的一段时间。 所以我试图减轻我的问题。 这是给我一个Permission denied因为它试图在/tmp下运行一个脚本。 在我的/etc/fstab ， /tmp被挂载为noexec 。 当我得到这个解决，我会看到如果安装Ruby 1.9.3工程更好。
更新2：发出mount -o remount,exec /tmp让我终于做了Ruby 1.9.3的安装。
