gulp和babel与gulp-live-server

Question

我正在尝试用ES6编写一个快速服务器而我正在使用Babel来进行转换,但是我无法使用gulp-live-server工作,因为我无法正常重启改变我的文件.

目前我有以下内容:

// gulpfile.babel.js

import gulp from 'gulp';
import gls from 'gulp-live-server';
import babel from 'gulp-babel';

gulp.task('transpile', ['clean:server'], () => {
  gulp.src(['server/**/*.js'])
  .pipe(babel())
  .pipe(gulp.dest('dist'));
});

gulp.task('server', ['transpile'], () => {
  var server = gls.new('dist/app.js');
  server.start();      
  gulp.watch(['server/**/*.js'], ['transpile']);
  gulp.watch('dist/app.js', server.start.bind(server)); //error
});

但它不起作用,此代码返回Gaze错误:

internal/child_process.js:274
  var err = this._handle.spawn(options);
                         ^

该错误与传递给watch的回调有关:server.start.bind(server)虽然这直接来自gls文档......

我没有看到我的更改反映出来,我似乎无法找到任何关于使用gls与转换器的文档.

请帮忙.

好的我已经修好了,我将为后代分享:由于某种原因,你必须将服务器重启功能包装在另一个功能上并自己执行.我认为这与Gaze包装子进程的方式有关.

gulp.watch('dist/app.js', () => server.start());

那就行了.
