Rethinkdb连接导致oob错误

Question

我正在使用rethinkdb和nodejs，但当我尝试运行基本示例时，它遇到了oob错误。我正在运行Ubuntu 14.04，并通过运行rethinkdb命令来运行rethinkdb服务器。

Rethinkdb命令输出：

$ rethinkdb
Recursively removing directory /home/tom/rethinkdb_data/tmp
Initializing directory /home/tom/rethinkdb_data
Running rethinkdb 2.3.0~0trusty (GCC 4.8.2)...

代码如下：

r = require('rethinkdb')
r.connect({ host: 'localhost', port: 28015 }, function(err, conn) {
  if(err) throw err;
}

这会导致以下错误：

buffer.js:559
  if (start > end) throw new Error('oob');
                         ^
    Error: oob

        at Socket.TcpConnection.rawSocket.once.handshake_callback (/home/tom/Downloads/rethink/node_modules/rethinkdb/net.js:692:46)
        at Socket.EventEmitter.emit (events.js:96:17)
        at TCP.onread (net.js:397:14)

请帮帮忙。谢谢。

我在运行Debian时遇到了一个(有点)类似的问题：

Creating a pool connected to 127.0.0.1:28015

buffer.js:247
  throw new TypeError(kFromErrorMsg);
  ^

在尝试了不同的rethinkdb版本(独立服务器和package.json依赖)，尝试了npm和node等的不同版本后，我在纯粹的挫折中安装了Ubuntu……但问题依然存在。

我的代码：

function connect() {
  return r.connect(config.get('rethinkdb'));
}

export function liveUpdates(io) {
  console.log('Setting up listener...');
  connect()
  .then(conn => {
    r
    .table('tickets')
    .changes().run(conn, (err, cursor) => {
      console.log('Listening for changes...');
      cursor.each((err, change) => {
        console.log('Change detected', change);
        io.emit('ticket-change', change);
      });
    });
  });
}

npm -v
