无法从Jekyll中的sass文件导入变量

我有一个variables.scss在我的根目录中保存所有sass变量的文件。我想将其导入我的其他scss文件中，以便可以使用以下变量：

@import "/variables.scss";

但是，当我运行项目时，出现以下错误：

转换错误：Jekyll :: Converters :: Scss在转换'assets / css / index.scss'时遇到错误：
找不到要导入的文件或文件不可读：/variables.scss。加载路径：第1行上的C：/Ruby25-x64/lib/ruby/gems/2.5.0/gems/minima-2.5.0/_sass

我在做什么错，如何正确导入我的sass变量。这是我的config_.yml文件：

# Welcome to Jekyll!

# This config file is meant for settings that affect your whole blog, values
# which you are expected to set up once and rarely edit after that. If you find
# yourself editing this file very often, consider using Jekyll's data files

#
# For technical reasons, this file is *NOT* reloaded automatically when you use
# 'bundle exec jekyll serve'. If you change this file, please restart the server process.

# Site settings
# These are used to personalize your new site. If you look in the HTML files,
# you will see them accessed via {{ site.title }}, {{ site.email }}, and so on.
# You can create any custom variable you would like, and they will be accessible
# in the templates via {{ site.myvariable }}.

  #permalink: '/page/:num' # Pages are html files, linked jekyll extensionless permalink style.

  category: 'posts'

  # Optional, the default tag to use, omit to disable

  # Optional, the default locale to use, omit to disable (depends on a field 'locale' to be specified in the posts,

  locale: '' 

 # Optional,omit or set both before and after to zero to disable. 
 # Controls how the pagination trail for the paginated pages look like.

    after: 2

  # Optional, the default file extension for generated pages (e.g html, json, xml).
  # Internally this is set to html by default
  extension: html

  # Optional, the default name of the index file for generated pages (e.g. 'index.html')
