javascript - mass.connectSync 不是一个函数

Question

为什么会出现这个错误，我运行 server.js 时，mass.connectSync 不是函数。它适用于我的mac，但不适用于我的windows。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，connect函数本身也不再存在，一路都是promise：

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，massive 需要 node > 6。如果您使用的是旧版本，则需要更新 node 才能使用 mass。
