当我使用 --watch 参数时出现 Sass 问题 [英] Sass issue when i use the --watch parameter

问题描述

当我执行该行时

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

我收到以下消息

<块引用><块引用><块引用>

Sass 正在关注变化.按 Ctrl-C 停止.NameError: 未初始化的常量 Listen::MultiListener使用 --trace 进行回溯.

正如您所说，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.

感谢任何帮助.

解决方案

我尝试了这些答案，但都没有奏效，所以我做了更多的研究.显然，问题出在 SASS 使用的 listen gem.Sass 只兼容 listen 0.7.

我能够通过运行以下两个命令(以 root 用户身份)来使其工作:

gem 卸载监听gem 安装监听 -v 0.7.3

When i execute the line

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

i get the following message

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

As you can say the process stops immediately and the watch option doesn't work.

What's the problem here ?? I have installed the Ruby 2.0.0-p0 version.

Any help appreciated.

解决方案

I tried these answers and none worked, so i did some more research. Apparently, the problem is with the listen gem that SASS is using. Sass is only compatible with listen 0.7.

I was able to get it working by running the following two commands (as root):

gem uninstall listen
gem install listen -v 0.7.3
