Question

我正在尝试在c9.io中运行node express但是我遇到问题它给了我这个错误我无法弄明白。我收到此错误消息。

$ node app.js
Server is running

/home/ubuntu/workspace/RESTful Routing/RESTfulBlogApp/node_modules/mongodb/lib/server.js:242
        process.nextTick(function() { throw err; })
                                      ^
Error: getaddrinfo ENOTFOUND localhost.restful_blog_app localhost.restful_blog_app:27017
    at errnoException (dns.js:27:10)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:78:26)

var bodyParser = require("body-parser"),
mongoose       = require("mongoose"),
express        = require("express"),
app            = express();

    mongoose.connect("mongodb://localhost.restful_blog_app");
    app.set("view engine", "ejs");
    app.use(express.static("public"));
    app.use(bodyParser.urlencoded({extended: true}));

    app.listen(process.env.PORT, process.env.IP, function(){
       console.log("Server is running"); 
    });

Answer 1

我认为这是public partial class Form2 : Form { public Form2() { InitializeComponent(); } public void ShowForm(List<EDIFile> EDIFiles) { DataGridView dataGridView1 = new DataGridView(); dataGridView1.AutoGenerateColumns = true; Controls.Add(dataGridView1); dataGridView1.DataSource = EDIFiles; this.ShowDialog(); } }

Answer 2

您还应该记得在运行服务器之前启动数据库。如果您仍然遇到问题，您应该尝试将localhost更改为127.0.0.1。

节点服务器没有运行 - 抛出process.nextTick（function（）{throw err;}）
