内部错误:无效UTF-8 - Sass &饮而尽

尝试在Linux Ubuntu中运行gulp sass时出现以下错误

hutber@hutber-ubuntu:/var/www/beta.norsemanfc.co.uk$ gulp sass
[14:43:26] Using gulpfile /var/www/beta.norsemanfc.co.uk/gulpfile.js
[14:43:26] Starting 'sass'...
[14:43:27] gulp-notify: [Compile Error] frontend/sass/style.scss
Internal Error: Invalid UTF-8
[14:43:27] Finished 'sass' after 547 ms

在所有文件/文件夹中搜索任何特殊字符都不会返回任何结果。

hutber@hutber-ubuntu:/var/www/beta.norsemanfc.co.uk$ find ./* -iregex '.*/.*[èö].*' -print

否则，如果我删除文件开头的@import，它将在@include border-box-sizing;因为这是susy

那么我怎么才能让sass在本地运行呢?

hutber@hutber-ubuntu:/var/www/beta.norsemanfc.co.uk/frontend/sass$ find ./* | xargs grep -i '.*/.*[èö].*'
grep: ./fonts: Is a directory

注:类似问题:错误&;Invalid utf -8&;当用@import编译sass时这是通过从路径中删除特殊字符来修复的，但是我所有的文件夹都是英文的，并且一直都是。
