我最近运行了 npm install，它更新了我所有的包。出于某种原因，这破坏了我的网络服务器（每当我尝试加载页面时，它只会加载一部分并死于此错误）。我尝试回滚版本的 socket.io、redis 和 nodetime，它们是出现在堆栈跟踪中的包，但是我没有运气让网络服务器再次工作。帮助？我在 OS X 上运行。

你安装了 MsgPack 吗？我用了之后

npm install msgpack

Socket.IO 会告诉我你发布的确切错误。

我通过卸载 MsgPack

npm uninstall msgpack

一切都恢复正常了。这不是问题的解决方案，但它是让您的系统重新运行的解决方法。

不幸的是，我的项目中需要 MsgPack，因此我无法使用此处列出的答案。

相反，我找到了这个页面： https ://github.com/LearnBoost/Socket.IO/wiki/Configuring-Socket.IO

这导致我进行了这些代码更改。

以前我有：

redis = require('redis'),
redisPub = redis.createClient(),
redisSub = redis.createClient(),
redisClient = redis.createClient(),
RedisStore = require('connect-redis')(express),
sessionStore = new RedisStore({
  client: redisClient
}),
socketRedisStore = require('socket.io/lib/stores/redis'),
socketRedis = require('socket.io/node_modules/redis'),

...

io.configure(function() {
  io.set('log level', 1);
  io.set('store', new socketRedisStore({
    redisPub: redisPub,
    redisSub: redisSub,
    redisClient: redisClient
  }));
  io.set('authorization', function(data, accept) {

...

进入这个：

redis = require('redis'),
redisPub = redis.createClient(),
redisSub = redis.createClient(null, null, {detect_buffers: true}),
redisClient = redis.createClient(),
RedisStore = require('connect-redis')(express),
sessionStore = new RedisStore({
  client: redisClient
}),
socketRedisStore = require('socket.io/lib/stores/redis'),
socketRedis = require('socket.io/node_modules/redis'),

...

io.configure(function() {
  io.set('log level', 1);
  io.set('store', new socketRedisStore({
    redis: redis,
    redisPub: redisPub,
    redisSub: redisSub,
    redisClient: redisClient
  }));
  io.set('authorization', function(data, accept) {

...

注意 redisSub 中包含的选项，用于检测缓冲区，然后将基本 redis 对象注入到 socket.io 存储配置中。
