RubyGem-在运行command:gem update--system时显示的一个gem错误

我是Ruby的一年级新生，现在正试图根据上的教程在我的机器上安装Ruby

但是，在我安装ruby186-26并运行命令“gem update--system”后，发生了以下错误：

同时，我们已经在其他机器上进行了试验，结果证明是正确的

因此，我的问题是，为什么错误发生在我的电脑上？你以前遇到过这种错误吗

这是由于您尝试安装的ruby版本导致的，其中包括一个无法自动更新自身的过时rubygems版本

由于您试图在windows计算机上安装ruby，因此需要从

获取您需要的任何版本的最新修补程序版本-有1.8.6、1.8.7和1.9.1安装程序可用

从该站点安装正确的版本后，您将能够运行

gem update--system

，而不会出现任何问题。

执行下面的命令及其工作原理

gem安装hpricot--platform=mswin32

Thx Bailey以获取您的回复。但是，在删除旧版本的Ruby并安装新版本（版本1.9.1-p378）之后，我们在推荐控制台中输入了以下推荐，结果是：------------C:\Documents and Settings\e482090\Desktop>gem-v 1.3.7 C:\Documents and Settings\e482090\Desktop>gem update——系统更新RubyGems错误：执行gem时。。。（错误号：：EINVAL）参数无效------------------------------------------我的环境是Windows XP Professional SP2，我的帐户属于管理员组。
