所以我正在尝试使用 babelify 但我无法让它工作？我错过了什么吗？在示例中，这是我的任务之一。我添加了 babelify，它运行良好，现在我需要添加 browserify。谢谢！ 

const config = require('./gulp.config.js')();
        const gulp = require('gulp');
        const gulpLoadPlugins = require('gulp-load-plugins');
        const plugs = gulpLoadPlugins();
        const bs = require('browser-sync');
        const env = process.env.NODE_ENV || 'local';
        const merge = require('merge-stream');
        const imagemin = require('gulp-imagemin');
        const browserify = require('browserify');
        const babelify = require('babelify');
        const clean = require('gulp-clean');
        const eventStream = require('event-stream');
        const optimize = false;
        const babel = require('gulp-babel'); 



       gulp.task('scripts-app', ['compile-jade'], () => {

          const scriptsStream = gulp.src(config.appFolder + '**/*.js'),
            templateCacheStream = gulp.src(config.appFolder + '**/*.html')
              .pipe(plugs.angularTemplatecache(config.templateCache.file, config.templateCache.options));
          console.log(plugs.order(config.jsOrder));

          return eventStream.merge(templateCacheStream, scriptsStream)
            .pipe(plugs.order(config.jsOrder))
            .pipe(plugs.concat(`${config.projectName}.js`))
            /*.pipe(browserify({
              insertGlobals: true,
              debug: true
            }))*/
            .pipe(babel({
              presets: ['es2015']
            }))
            .pipe(plugs.if(optimize, plugs.uglify()))
            .pipe(gulp.dest(config.build));

        });

这是我运行任务时得到的错误日志，显然我做错了什么
