node.js - 语法错误：无效或意外的令牌

Question

我正在尝试连接到 mongoose，但是当我需要顶部的 mongoose 包时，它会抛出一个错误“语法错误：无效或意外的令牌”。即使我评论了我的模型，它也不会改变。

应用程序.js

const express = require("express");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");

const feedRoutes = require("./routes/feed");

const app = express();

app.use(bodyParser.json());

app.use(feedRoutes);

mongoose
.connect(
 "mongodb+srv://name:[e-mail]/barber",
 { useNewUrlParser: true, useUnifiedTopology: true }
)
.then(result => {
 app.listen(8080);
 console.log("connected");
})
.catch(err => console.log(err));

我的模型 post.js

const mongoose = require("mongoose");

const Schema = mongoose.Schema;

const postSchema = new Schema(
{
  name: {
    type: String,
    required: true
  },
  age: {
    type: Number,
    required: true
  },
  phone: {
    type: Number,
    required: true
  },
  email: {
    type: String,
    required: false
  }
},
{
  timestamps: true
}
);

module.exports = mongoose.model("Post", postSchema);

这就是错误

谢谢你的帮助。

似乎是 postSchema 中的一个错误的括号，位于电子邮件和时间戳之间。下面的片段有效吗？

const postSchema = new Schema(
{
  name: {
    type: String,
    required: true
  },
  age: {
    type: Number,
    required: true
  },
  phone: {
    type: Number,
    required: true
  },
  email: {
    type: String,
    required: false
  },
  {
  timestamps: true
  }
});
