今天 gulp 一个项目编译 sass 时提示

Encoding::CompatibilityError: incompatible character encodings: GBK and UTF-8
  Use --trace for backtrace.

解决步骤

一：gulp-ruby-sass 配置--trace定位错误

• sass(source, [options]) 在 options 里配置{trace: true}

  const gulp = require('gulp'); const sass = require('gulp-ruby-sass');

  gulp.task('sass', () => sass('source/file.scss', {trace: true}) .on('error', sass.logError) .pipe(gulp.dest('result')) );

找到错误信息

注意 sass 版本！！！

 C:/Ruby24-x64/lib/ruby/gems/2.4.0/gems/sass-3.5.5/lib/sass/importers/filesystem.rb:87:in `index': incompatible character encodings: GBK and UTF-8 (Encoding::CompatibilityError)
    from C:/Ruby24-x64/lib/ruby/gems/2.4.0/gems/sass-3.5.5/lib/sass/importers/filesystem.rb:87:in `remove_root'

排除错误（将 gbk 转为 utf-8 编码）

http://ruby-doc.org/core-2.5.1/String.html#method-i-encode

• encode(dst_encoding, src_encoding [, options] ) → str
  （目标编码，原编码，[选项]）

87 行改为：if name.encode("utf-8", "gbk").index(@root + "/") == 0
