usemin ()不处理.js文件

Question

我使用一个gulp任务来对CSS和JavaScript文件进行版本化和丑化，但是它没有对.js文件进行版本控制，也没有解释，因为它根本没有抛出任何错误或警告。知道怎么解决吗？

// build.js file
var gulp = require('gulp'),
    imagemin = require('gulp-imagemin'),
    del = require('del'),
    usemin = require('gulp-usemin'),
    rev = require('gulp-rev'),
    cssnano = require('gulp-cssnano'),
    uglify = require('gulp-uglify'),
    gutil = require('gulp-util');

gulp.task('deleteDistFolder', function() {
    return del("./dist");
});

gulp.task('optimizeImages', ['deleteDistFolder'], function() {
    return gulp.src(["./travel-app/assets/images/**/*",
                "!./travel-app/assets/images/icons",
                "!./travel-app/assets/images/icons/**/*",
            ])
                .pipe(imagemin({
                    progressive: true,
                    interlaced: true,
                    multipass: true
                }))
                .pipe(gulp.dest("./dist/assets/images"));
});

gulp.task('usemin', ['deleteDistFolder'], function() {
    return gulp.src("./travel-app/index.html")
                .pipe(usemin({
                    css: [  function() {return rev()}, 
                            function() {return cssnano()}
                         ],
                    js: [   function() {return uglify()}, 
                                function() {return rev()}
                        ]
                }))
                
                .pipe(gulp.dest("./dist"))
});

gulp.task('build', ['deleteDistFolder', 'optimizeImages', 'usemin']);

<!-- html blocks -->

  <!-- build:css /assets/styles/styles.css -->

问题似乎与ES6的使用有关，所以最好使用gulp-uglify-es包。
