Jekyll 和 Sass 无法编译 Sass 文件

Question

我刚刚开始使用Yeoman生成器启动一个新的Jekyll项目它是使用 sass ut 配置的，我无法让它工作

我在_sass文件夹中只有一个文件，即 main.scss，它以

@charset "utf-8";

但是当我启动咕噜咕噜服务时，我得到这个：

Running "copy:stageCss" (copy) task
[D] Task source: /Users/alexandresagette/Development/jekyll-site/node_modules/grunt-contrib-copy/tasks/copy.js
Verifying property copy.stageCss exists in config...OK
Options: encoding="utf8", processContent=false, processContentExclude=[], mode=false

Done, without errors.

  Use --trace for backtrace. Use --force to continue.

gruntfile可以在这里找到：https://github.com/robwierzbowski/generator-jekyllrb/blob/master/app/templates/Gruntfile.js

有人可以帮我吗？

我一个接一个地运行咕噜咕噜的服务任务，发现它实际上是错误的sass任务：

    grunt --trace sass:server
Running "clean:server" (clean) task
>> 1 path cleaned.
Running "jekyll:check" (jekyll) task
`jekyll doctor` was initiated.

Jekyll output:
Configuration file: /Users/alexandresagette/Development/jekyll-site/_config.yml
  Your test results are in. Everything looks fine.
Running "sass:server" (sass) task
NoMethodError: undefined method `ascii_only?' for nil:NilClass
  Use --trace for backtrace.
Warning: Exited with error code 1 Use --force to continue.
Aborted due to warnings.
