Question

我在端口27017启动服务器后，打开另一个窗口并运行我的服务器程序，它显示连接错误如下

C:\node-mongodb\node_modules\mongodb\lib\server.js:242
process.nextTick(function() { throw err; })
                              ^

我尝试删除锁定文件修复mongodb和其他类似问题的解决方案，但它们无法正常工作。请告诉我为什么会出现这个错误以及如何解决它。我正在运行Windows XP（32位）。这是simple-server.js文件：

var MongoClient = require('mongodb').MongoClient,
assert = require('assert');

// Connection URL
var url = 'mongodb://localhost:27017/test';
// Use connect method to connect to the Server
MongoClient.connect(url, function (err, db) {
assert.equal(err,null);
console.log("Connected correctly to server");
    var collection = db.collection("dishes");
    collection.insertOne({name: "nerd21", description: "test"},
  function(err,result){
    assert.equal(err,null);
    console.log("After Insert:");
    console.log(result.ops);
    collection.find({}).toArray(function(err,docs){
       assert.equal(err,null);
       console.log("Found:");
       console.log(docs);
       db.dropCollection("dishes", function(err, result){
           assert.equal(err,null);
           db.close();
           });
    });
});

}）;
