使用Gulp + Watchify + Factor包检测到可能的EventEmitter内存泄漏

Question

我正在使用gulp，browserify，watchify和factor bundle来开发几个javascript文件。一切工作正常，节选了一段时间后，我开始看到这样的警告：

下面是我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，我应该什么地方设置最大的听众，但恐怕这可能是一个正版的记忆泄漏。

Answer 1

我的初始解决方案没有工作，它看起来真的是一个错误。我想我已经找到了一个临时的修补程序。

编辑node_modules/factor-bundle/index.js和改变

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

您的原始代码应工作。
