我有如下的大量任务脚本, // loads various gulp modules var gulp = require('gulp'); var concat = require('gulp-concat'); var minifyCSS = require('gulp-minify-css'); var autoprefixer = require('gulp-autoprefixer'); var rename = require('gulp-rename'); // create task gulp.task('css', function(){ gulp.src('src/css/**/*.css') .pipe(minifyCSS()) .pipe(rename('style.min.css')) .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9')) .pipe(gulp.dest('dist/css')) }); 如何将src / css中的所有css文件都缩小为dist / css / style.min.css文件?
