ruby - Sass --watch抛出错误 “NameError: uninitialized constant Listen::Listener”

Question

我在跑;

sass --watch --style compressed --sourcemap css/sass:css

我得到了；

NameError: uninitialized constant Listen::Listener

用--trace运行它给了我；

>>> Sass is watching for changes. Press Ctrl-C to stop.

我很难解决该问题；它看起来是我的SCSS文件中的错误以及如何将它们组合在一起，还是我的Sass gem/安装有问题？

编辑:版本详细信息

Sass 3.3.0.rc.3 (Maptastic Maple)
ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]

问题似乎是一个已知的problem with RC3 of Sass 3.3，我正试图将其用于Sourcemaps支持。我在另一个盒子上使用了较早的RC，它可以正常工作，因此尝试在此处安装RC2即可解决此问题。

sudo gem uninstall sass
...
sudo gem install sass -v 3.3.0.rc.2
