我正在尝试通过使用nodemailer和node.js并通过express的输入表单，使用gmail发件人地址发送电子邮件。我一直收到错误响应代码554。因此，我安装并需要SMTP传输，但仍然收到错误。我是否错过了导致此错误的nodemailer安装步骤

app.j

var Express = require("express");
var app =Express();

var port = process.env.PORT || 3000;
app.set("view engine","ejs");

var bodyParser = require("body-parser");
app.use(bodyParser.urlencoded({extended: true}));

var smtpTransport = require('nodemailer-smtp-transport');

var nodemailer= require("nodemailer");
var transporter=nodemailer.createTransport(smtpTransport({
    service: 'outlook',auth: {

        user: 'antonyt@live.com',pass: 'passcode123'
    }
}));

app.use(Express.static("public"));

var images=[
    {name: "Logo",image:"/images/pic.png"},{name: "Logo",image:"/images/beforeboat.jpg"},image:"/images/completedboat.jpg"},image:"/images/inprogressboat.jpg"},image:"/images/inprogressboat.jpg"}]

app.get("/gallery",function(req,res){
    res.render("gallery",{images:images});
});

app.get("/",res){

        res.render("home");

});

app.get("/contact",res){

        res.render("contact");

});

app.post("/contact",res){
    var name = req.body.name;
    var email = req.body.email;
    var message= req.body.message;

    var mailOptions={
        from: email,to:   'antonyt@live.com',subject: req.body.name,text: req.body.message
    };

    transporter.sendMail(mailOptions,function(error,info){
            if(error){
                console.log(error);
            }
            else{

                console.log('email sent:' + info.response);
            }


    });




});

app.listen(port,function(){

    console.log("Server started boys!")
});
