无法导入护照本地猫鼬

Question

即使一切正确，我仍然收到此错误。我已经交叉检查了教程中的所有内容，甚至是如何逐行导出模块。 MongoDB shell 在后台运行。

xyz/authdemo/node_modules/passport-local-mongoose/index.js:125

  .then(({ user }) => {
         ^


SyntaxError: Unexpected token {

这是我的app.js

var express                 = require("express"),
    mongoose                = require("mongoose"),
    passport                = require("passport"),
    bodyParser              = require("body-parser"),
    LocalStrategy           = require("passport-local"),
    passportLocalMongoose   = require("passport-local-mongoose");

mongoose.connect("mongodb://localhost/auth_demo_app");

var app = express();

app.set("view engine", "ejs");

app.get("/", function(req, res){
    res.render("home");
});

app.get("/secret", function(req, res){
    res.render("secret");   
})

app.listen(3000, function(){
    console.log("Authentication server started");
});

请更正代码并指出错误。谢谢
