嗨，伙计们，我在连接到 orientdb 数据库时遇到了一些麻烦。

这是我的 app.js 代码

const express = require('express');
const app = express();
const path = require('path');
const router = express.Router();
const OrientJs = require('orientjs');


var server = OrientJs({
    host: "localhost",
    password: "root",
    username: "root",
    useToken: true
});

var db = server.use({
    name: 'demodb',
    username: 'admin',
    password: 'root',
    useToken: true
});

server.list()
    .then(function (dbs) {
        console.log( dbs.length + ': database/s on the server.');
    });


db.select().from('ArchaeologicalSites').all()
    .then(function (result) {
        console.log(result);
    });

app.set('view engine', 'pug')

router.get('/', function (req, res) {
    res.sendFile(path.join(__dirname + '/views/index.html'));
});

即使我尝试在 server.use() 函数中更改密码或用户名，调试器也会显示此消息。

来自调试器的消息：

1: database/s on the server.

所以...它正确连接到 server.use()，实际上 server.list() 工作正常。但是当涉及到查询时，它表明 var "db" 可能有问题......

当我将 app.js 更改为此：

var db = server.use({
    name: 'demodb',
    username: 'root',
    password: 'root',
    useToken: true
});

显示的错误是这样的：
