当我使用 --watch 参数时出现 Sass 问题

Question

当我执行该行时

$sass --watch sass/views.scss:views.css

我收到以下消息

Sass is watching for changes. Press Ctrl-C to stop. NameError: uninitialized constant Listen::MultiListener Use --trace for backtrace.

正如您可以说该过程立即停止并且监视选项不起作用。

这里有什么问题？？我已经安装了 Ruby 2.0.0-p0 版本。

任何帮助表示赞赏。

我尝试了这些答案，但没有一个奏效，所以我做了更多的研究。 Apparently ，问题出在 listen SASS 正在使用的 gem。 Sass 只与听 0.7 兼容。

我能够通过运行以下两个命令(以 root 用户身份)使其工作:

gem uninstall listen
gem install listen -v 0.7.3
