node.js - 运行时获取意外 token

Question

通过 cmd 运行此代码时，我收到此错误。该错误表明它位于第 1 行。 7 但没找到。

var express = require('express'),
filter = express(),
server = require('http').createServer(filter),
io = require('socket.io').listen(server),
mongoose = require('mongoose'),

server.listen(1149, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1149/');

mongoose.connect('mongodb://localhost/chat', function(err){
    if(err){
        console.log(err);
    } else{
        console.log('Connected to mongodb!');
    }
});

var filter_CheckBoxSchema = mongoose.Schema({
category : { type: Boolean, default: false },
created: {type: Date, default: Date.now}
});

我收到错误:

C:\node\people discovery app\filter.js:7
server.listen(1149, '127.0.0.1');
      ^

Answer 1

从第一行开始的变量声明永远不会完成，因此语句:

server.listen(1149, '127.0.0.1');

被视为变量声明，但这里不是有效的语句。

要解决此问题，您可以从第一行开始使用 ; 来完成 var 语句，例如:

var express = require('express'),
filter = express(),
server = require('http').createServer(filter),
io = require('socket.io').listen(server),
mongoose = require('mongoose'); // <-- Notice the ';' here

server.listen(1149, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1149/');
