使用gulp-clean-css和gulp-rename
示例
首先，安装gulp，gulp-clean-css并gulp-rename在本地项目目录中
npm install --save-dev gulp gulp-clean-css gulp-rename
比将以下minify-css任务添加到您的gulpfile.js
var gulp = require('gulp');
var cleanCSS = require('gulp-clean-css');
var rename = require('gulp-rename');
gulp.task('minify-css', function() {
return gulp.src('css/dist/dist.css')
.pipe(cleanCSS())
.pipe(rename('dist.min.css'))
.pipe(gulp.dest('css/dist'));
});
gulp.task('watch', function(){
gulp.watch('css/dist/**/*.css', ['minify-css']);
//其他观察者
});
gulp.task('default', ['minify-css', 'watch']);在这里执行文件的缩小并将其重命名为.pipe(cleanCSS())css/dist/dist.css.pipe(rename('concat.min.css'))dist.min.css
