Node.js socket.io：TypeError Object（）{[native code]}没有方法'assign'

Question

我有2台服务器具有完全相同的设置。但是在1台服务器上，我遇到了错误而在另一台服务器上运行良好。

在服务器1上：

[root@tst socketio]# npm list socket.io
/var/socketio
└── socket.io@2.0.4 

Package nodejs-0.10.48-3.el6.x86_64 already installed and latest version

在服务器2上：

[root@1 socketio]# npm list socket.io
/var/socketio
└── socket.io@2.0.4 

Package nodejs-0.10.48-3.el6.x86_64 already installed and latest version

服务器1上的脚本：

[root@tst socketio]# node /var/socketio/socketioclient.js 1768
Time: 5/3/2018 21:10:6
ID: 1768
Start connect
S-connection

服务器2上的脚本：

[root@1 socketio]# node /var/socketio/socketioclient.js 1768
Time: 5/3/2018 20:59:24

我的socketioclient.js：

console.log(datetime);
console.log('ID: '+ID);
var io = require('socket.io-client');
console.log('Start connect');
var sSocket = io.connect('https://11.22.33.44:1234', {
    reconnection: true,
    reconnectionDelay: 1000,
    reconnectionDelayMax : 5000,
    reconnectionAttempts: 3
});
sSocket.on('connect', function (data) {

    console.log('S-connection');
    console.log(sSocket.id);

        console.log('S-emit event');
        sSocket.emit('event', { ID: ID });
        sSocket.disconnect();

    }

    sSocket.on('serveroutput', function (data) {
        console.log('S-serveroutput: '+data);
    });

});

sSocket.on('disconnect', function (data) {
    console.log('S-disconnect');
});

sSocket.on('reconnect', function() {
    console.log('S-reconnecting');
});

sSocket.on('reconnect_failed', function (data) {
    console.log('S-reconnect failed');
});

我认为socketio版本或nodejs版本没有区别。但结果却不同。怎么会？

我已经阅读（在这个网站上）有关需要节点版本> = 4.但是因为它适用于1台服务器，我不认为这是问题所在。
