Question

我不知道为什么它总是会弹出SyntaxError意外的输入结束在Object.runInThisContext的createScript处。我尝试了很多方法来解决它，但它仍然无法正常工作！希望有人能纠正，如果我错了！谢谢!!!!!!!

在命令行上写：

npm i socket.io express -s

var fs = require('fs')
//https的一些設定
var options = {
   key: fs.readFileSync('/etc/letsencrypt/live/awiclass.monoame.com/privkey.pem'),
   cert: fs.readFileSync('/etc/letsencrypt/live/awiclass.monoame.com/fullchain.pem')
}

//https & socket port
var https = require('https').createServer(options);
https.listen(4040)
var io = require('socket.io')(https);

console.log("Server socket 4040 , api 4000")

//api port
var app = require('express')();
var port = 4000;
app.listen(port, function(){
   console.log('API listening on *:' + port);
});


var messages = [];

//用api方式取得
app.get('/api/messages',function(req,res){
   res.send(messages);
})

io.on('connection', function(socket){
   //初始化...
   console.log("A user connected.");
   io.emit("allMessage",messages);

   socket.on('sendMessage',function(obj){
      //get all message!
      messages.push(obj);
      console.log( obj.message + " - " + obj.name )
      io.emit('newMessage', obj);
   })
})

错误：

SyntaxError: Unexpected end of input

在命令行上：socket.io，javascript，node.js
