我正在尝试将我的应用程序配置为将 browserify 与 watchify 和 factor-bundle 一起使用。但是，我似乎要么最终导致内存泄漏，要么破坏 watchify 触发的构建。

我的 build.js

var browserify = require('browserify'),
    watchify = require('watchify'),
    fromArgs = require('watchify/bin/args'),
    fs = require('fs');

var inputs = [
  './client/src/application.js'
];

var outputs = [
  'app/assets/javascripts/bundles/application.js'
];

var commonOutput = 'app/assets/javascripts/bundles/common.js';

var bundle = function(b){
  b.plugin('factor-bundle', { outputs: outputs });
  b.transform('browserify-shim');
  b.bundle().
    on('error', function(err) {
      console.log(err.toString());
      this.emit('end');
    }).
    pipe(fs.createWriteStream(commonOutput));
};

var watcher = watchify(browserify(watchify.args));

watcher.add(inputs);    
watcher.on('update', function(ids) {
  bundle(watcher);
  console.log('updated with ids:', ids);
});

watcher.on('log', function(msg) {
  console.log(msg);
});

bundle(watcher);

通过这种配置，我最终得到：

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.

...

我认为这是因为我每次都在创建该写入流并且没有收集旧的？但我想不出正确的方法来做到这一点。
