gulp-concat没有将我的jsx文件转换为js with reactify

Question

我是Gulp的新手，我正在尝试使用browserify将jsx文件转换为js文件并重新执行但是我得到了错误。我的gulp文件看起来像这样：

var gulp = require('gulp'),
    nodemon = require('gulp-nodemon'),
    browserify = require('browserify'),
    reactify = require('reactify'),
    concat = require('gulp-concat'),

gulp.task('bundler', function() {
    gulp.src('public/javascript/app.jsx')
        .pipe(browserify({
            transform: 'reactify',
            extensions: ['.jsx']
        }))
        .pipe(concat('main.js'))
        .pipe(gulp.dest('./dist/javascript'));
});

gulp.task('server', function() {
    nodemon({
        script: 'server.js',
        ext: 'html js',
        watch: 'public'})
        .on('restart', function() {
            console.log('Restarted');
        });
});

gulp.task('default', ['bundler', 'server']);

但是我收到了这个错误：

之前工作正常，但突然间它停止了工作。我一直试图解决它几个小时但我找不到它不起作用的原因，我真的很感激一些帮助。
