Css 要导入的Sass文件找不到或不可读，文件不存在

我正在编写一个ruby脚本，将SCS编译成CSS，但它似乎找不到我要导入的文件

这是我的ruby脚本，非常基本

require "sass"

template = File.read("brand_oit_appdev.scss")

puts template

options = {
  :syntax => :scss
}

render = Sass::Engine.new(template, options).render

puts render

这里是brand_oit_appdev.scss

我没有办法解决这个问题。我已经验证了该文件是可读的，因为我能够从ruby命令读取它

有人能帮我吗？

您需要用加载路径更新Sass:：Engine选项。例如：

options = {
  :syntax => :scss,
  :load_paths => [ './' ]
}
