运行 gulp-uncss 以摆脱所有未使用的代码时遇到问题。该错误似乎与解析css有关。

C:\wamp64\www\css-cleanup\node_modules\gulp-uncss\node_modules\uncss\node_modules\bluebird\js\release\async.js:48
        fn = function () { throw arg; };
                           ^

我的 gulpfile.js 看起来像这样：

var gulp = require('gulp');
var uncss = require('gulp-uncss');

gulp.task('default', function () {
    return gulp.src('sass/**/*.scss')
        .pipe(uncss({
            html: ['index.html']
        }))
        .pipe(gulp.dest('./css_new/'));
});
