我按照http://docs.sencha.com/extjs/4.2.0/#!/guide/theming中的步骤操作， 但是当我想通过sencha app build命令构建应用程序时出现以下错误。

（注意：我的操作系统是 win 7 x64，我使用ruby​​installer-2.0.0-p0-x64安装程序安装了 rubby，然后通过SenchaCmd-3.1.1.274-windows.exe安装程序安装了 Sencha 命令。我还通过常规命令提示符窗口和“使用 Ruby 启动命令提示符”，但错误相同。）

在此之后，我通过gem install sass命令安装了 SASS，它安装了 SASS 3.2.8（虽然 Sencha Command 说我们自己安装 SASS 时不需要安装它：Introduction to Sencha Cmd）......但是同样的错误。

我还通过gem install compass（版本：0.12.2）安装了指南针并Sencha app build再次执行命令......并收到同样的错误......

有什么帮助吗？！

我有同样的问题。似乎 extjs 与 ruby​​ 版本 2.x 不兼容我读到一些用户遇到了同样的问题。

卸载 ruby​​ 2 并安装 1.9.3 后它应该可以工作。

PS 正如我从文档中了解到的那样，您不需要安装 sass 和 compass，因为它已经是 sencha cmd 的一部分
