Ruby 在windows 7上安装精简版时出现的问题

我对ruby是新手。我正在尝试安装ruby gem thin。它显示安装gem时出错。我在谷歌上搜索错误，但找不到解决我问题的链接

错误是：

非常感谢您的帮助。谢谢。

我通过以下步骤解决了问题。发布此答案，因为它可能对其他人有用

我卸载并删除了所有ruby内容，然后重新启动了机器。从这里下载了Ruby 2.0和Devkit

安装了ruby和devkit。使用此链接中给出的说明安装devkit

---

cd to ruby文件夹和已安装的rails，thin gem

我得到的错误可能与您指出的错误不同。但不管怎样，我尝试了那些建议。
