Question

每当我尝试从 mongoose 连接到我的 mongo 服务器时，都会出现此错误。我已经安装了 MongoDB，我正在使用命令 mongod 运行我的服务器，我可以与 mongo shell 交互并使用那里的所有命令。

我之前曾尝试使用 mongoose 连接到此端口，并且它可以正常工作。 我还尝试使用不同的端口号并删除 DB 文件并重新创建它。但还是一样的错误日志

尽管如此，我也安装了 mongoose，并且 npm 工作正常

我的代码

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/test', {useNewUrlParser: true, useUnifiedTopology: true})
    .then(() => {
        console.log("Connected");
    })
    .catch(err => {
        console.log('Error');
        console.log(err);
    })

错误 MongooseServerSelectionError：连接 ECONNREFUSED 127.0.0.1:27017
