我正在使用 gulp、browserify、watchify 和 factor bundle 来构建几个开发中的 javascript 文件。一切正常，除了一段时间后我开始看到这个警告：

下面是我的 gulpfile

var gulp = require('gulp');
var gutil = require('gulp-util');
var source = require('vinyl-source-stream');
var browserify = require('browserify');
var reactify = require('reactify');
var watchify = require('watchify');
var factor = require('factor-bundle');
var uglify = require('gulp-uglify');
var fs = require('fs');
var concat = require('concat-stream');
var file = require('gulp-file');

gulp.task('watch', bundle)

function bundle () {

  // react components
  var files = [
    '/path/to/file1.jsx',
    '/path/to/file2.jsx',
    '/path/to/file3.jsx'
  ];


  var bundler = watchify(browserify(watchify.args)) 

  bundler.add(files);
  bundler.add('./lib/api.js', {expose: 'api'});
  bundler.require('./lib/api.js', {expose: 'api'});
  bundler.transform('reactify');
  bundler.on('update', rebundle);

  function rebundle() {
    bundler.plugin('factor-bundle', {
        outputs: [
          write('/path/to/file1.js'),
          write('/path/to/file2.js'),
          write('/path/to/file3.js'),
          ]
    });
    bundler.bundle()
        .on('error', gutil.log.bind(gutil, 'Browserify Error'))
        .pipe(write('shared.js'));
  };

  return rebundle();
}


function write (name) {
    return concat(function (content) {
        // create new vinyl file from content and use the basename of the
        // filepath in scope as its basename.
        return file(name, content, { src: true })
        // uglify content
        .pipe(uglify())
        // write content to build directory
        .pipe(gulp.dest('./public/bundles/'))
    });
}

我读到我应该在某个地方设置最大听众，但我担心这可能是一个真正的内存泄漏。

我最初的解决方案不起作用，看起来它确实是一个错误。我想我找到了一个临时的hacky修复。

编辑node_modules/factor-bundle/index.js和更改

从 b.on('reset', addHooks); 到 b.once('reset', addHooks);

您的原始代码应该可以工作。

这是任何保持得分的人的GitHub 问题：D
