运行gulp命令，提示"ReferenceError uglify is not defined"

Question

• 在学gulp工具，参考这个博客文章敲的代码

• 在npm把gulp和gulp-uglify都安装了，然后运行gulp命令，出现如下错误：

$ gulp
[18:01:43] Using gulpfile E:\workspace_node\gulpDemo\gulpfile.js
[18:01:43] Starting 'default'...
[18:01:43] 'default' errored after 5.39 ms

• app.js代码：

console.info("hello wolrd gulp");

• gulpfile.js

var gulp = require('gulp');
gulp.task('default',function(){
  gulp.src('app.js')
  .pipe(uglify())
  .pipe(gulp.dest('dist/'));
});

你还要多加一句，不然gulp不知道uglify是什么东东哦：

var uglify = require('uglify');

然后gulp有专门适配的gulp-uglify插件，一般应该是用gulp-uglify的吧
