massive.connectSync 不是一个函数

Question

为什么我会收到此错误，当我运行服务器时，massive.connectSync 不是一个函数.js。它适用于我的Mac，但不适用于我的窗口。请帮助解决此enter code here错误

var express = require("express");
var app = express();
var http = require('http');
var massive = require("massive");
var connectionString = "postgres://massive:@localhost/MarketSpace";
// connect to Massive and get the db instance. You can safely use the
// convenience sync method here because its on app load
// you can also use loadSync - it's an alias
var massiveInstance = massive.connectSync({connectionString : connectionString})
// Set a reference to the massive instance on Express' app:
app.set('db', massiveInstance);
http.createServer(app).listen(8080);

Answer 1

不再支持同步函数，连接函数本身也不再存在，都是一路承诺：

var express = require("express");
var app = express();
var http = require('http');
var massive = require("massive");
var connectionString = "postgres://massive:@localhost/MarketSpace";
massive(connectionString).then(massiveInstance => {
app.set('db', massiveInstance);
http.createServer(app).listen(8080);
});

请注意，大量需要节点> 6。如果您使用的是旧版本，则需要更新节点才能使用大量。
