Ruby on rails 无法加载这样的文件--pty（LoadError）

RubyonRails是全新的。我的环境是Windows 2008 R2，我只使用 RailsInstaller来安装它。我得到了一个网站，所以我把它放在C:\Sites下。 我按照指南安装了rails，正如您在代码中看到的版本一样。 然后我运行“rails服务器”尝试启动该服务，但收到了关于的错误消息“therubyracer-heroku-0.8.1.pre3没有安装，所以我在那之后安装了gem和bundle。然后therubyracer heroku抛出了一堆错误，所以我查了一下，告诉我需要将它打包成一个组，我这样做了，并从gem文件的生产组中删除了它。现在，当我进行“捆绑安装”时，一切都很好，所以我继续使用“rails服务器”，下面是错误消息。有什么帮助吗？请

从Gemfile中删除zeus gem，运行

捆绑安装

，然后重试

rails服务器

删除。但是关于activesupport、bundler或railties，这是windows的路径问题吗？不，这三个方面都很好
