NodeJS集群意外的assert.AssertionError
我正面临一个奇怪的错误，这是我的主要.js文件
var cluster = require('cluster'), express = require('express'), http = require('http'); if (cluster.isMaster) { var cpuCount = require('os').cpus().length; for (var i = 0; i < cpuCount; i += 1) { cluster.fork(); } } else { var app = express(), server = http.createServer(app), io = require('socket.io').listen(server); io.set('log level', 2); server.listen(3000); } cluster.on('exit', function (worker) { console.log('Worker ' + worker.id + ' died :('); cluster.fork(); }); 这是我得到的错误消息..
Worker 1 died :( Worker 2 died :( assert.js:92 throw new assert.AssertionError({ ^ AssertionError: false == true at Cluster.cluster.fork (cluster.js:500:3) at Cluster.<anonymous> (/xxx/x/xxx/xxx/xxxxx.js:21:13) at Cluster.EventEmitter.emit (events.js:106:17) at process.<anonymous> (cluster.js:341:13) at process.g (events.js:180:16) at process.EventEmitter.emit (events.js:95:17) at process.exit (node.js:707:17) at process.<anonymous> (cluster.js:545:15) at process.g (events.js:180:16) at process.EventEmitter.emit (events.js:117:20) assert.js:92 throw new assert.AssertionError({ ^ AssertionError: false == true at Cluster.cluster.fork (cluster.js:500:3) at Cluster.<anonymous> (/xxx/x/xxx/xxx/xxxxx.js:21:13) at Cluster.EventEmitter.emit (events.js:106:17) at process.<anonymous> (cluster.js:341:13) at process.g (events.js:180:16) at process.EventEmitter.emit (events.js:95:17) at process.exit (node.js:707:17) at process.<anonymous> (cluster.js:545:15) at process.g (events.js:180:16) at process.EventEmitter.emit (events.js:117:20)
不知道有什么错在那里有任何帮助？

cluster.js行500是
assert(cluster.isMaster);
即你从另一个worker调用fork （或Node认为你是）。
如果将cluster.on('exit' if (cluster.isWorker)移动到if (cluster.isWorker)块中并不能解决问题，那么我认为你应该在Github上打开一个问题，因为我不明白为什么事件会在任何工人。
编辑： 这确实是一个错误 。
有同样的问题 – 这是现在的工作：
cluster.on('disconnect', function(worker) { if (this.isMaster) { console.log('worker ' + worker.process.pid + ' disconnected'); cluster.fork(); } });
