How do I call a sass function from inside a ruby file?

如何在ruby文件中调用sass函数?

The following line works in the command prompt:

sass C:\Users\..etc..\main.scss

I need to put this into a Ruby file. So I wrote as below in a Ruby file:

我需要把它放到一个Ruby文件中。所以我在Ruby文件中写了如下:

require 'sass'

Set the options as you need, then use Sass::Engine#render.

根据需要设置选项,然后使用Sass :: Engine#render。

require "sass"
options = {
  cache: true,
  syntax: :sass,
  style: :compressed,
  filename: original_file_name,
  ...
}
render = Sass::Engine.new(File.read(original_file_name), options).render
File.write(output_file_name, render)

If you've already installed the Sass gem, you can run it from the Command Line. To use Sass in your ruby script, you need to make a Sass object and then use the functions associated with it.

如果您已经安装了Sass gem,则可以从命令行运行它。要在ruby脚本中使用Sass,您需要创建一个Sass对象,然后使用与之关联的函数。
