其中agencySource...后面的是路徑，壓縮代碼的時候報錯，不知道該怎么壓縮代碼了？

    gulp.task('agency:cache-templates', function() {
                    var options = {
                        removeComments: true, //清除HTML注釋
                        collapseWhitespace: true, //壓縮HTML
                        collapseBooleanAttributes: false, //省略布爾屬性的值 <input checked="true"/> ==> <input />
                        removeEmptyAttributes: true, //刪除所有空格作屬性值 <input id="" /> ==> <input />
                        removeScriptTypeAttributes: true, //刪除<script>的type="text/javascript"
                        removeStyleLinkTypeAttributes: true, //刪除<style>和<link>的type="text/css"
                        minifyJS: true, //壓縮頁面JS
                        minifyCSS: true //壓縮頁面CSS
                    };
                    return gulp.src([agencySource.js.staticViews, agencySource.js.views])
                        .pipe(htmlmin(options))
                        .pipe(templateCache('app.js', {
                            root: 'views',
                            module: 'app'
                        }))
                        .pipe(gulp.dest(agencySource.build.cache));
                });
                
                gulp.task('agency:build', ['agency:cache-templates'], function() {
                    
                    agencySource.js.src.push(agencySource.build.cache + '/app.js');
                    return gulp.src(agencySource.js.src)
                        .pipe(ngAnnotate())
                        //.pipe(uglify())
                        .pipe(concat('app.js'))
                        .pipe(gulp.dest(agencySource.build.cache));
                });
   
   
   
   我在 `https://www.npmjs.com/package/gulp-uglify`中找到了，但是不知道怎么用？
   var uglifyjs = require('uglify-js'); // can be a git checkout 
                                             // or another module (such as `uglify-es` for ES6 support) 
        var composer = require('gulp-uglify/composer');
        var pump = require('pump');
         
        var minify = composer(uglifyjs, console);
         
        gulp.task('compress', function (cb) {
          // the same options as described above 
          var options = {};
         
          pump([
              gulp.src('lib/*.js'),
              minify(options),
              gulp.dest('dist')
            ],
            cb
          );
        });

大佬們幫我看看、、、、謝謝?。?！
