如何在mongoose虚拟环境中使用anync await？

const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/mydatabase', {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});

const userSchema = new mongoose.Schema({
  name: String,
  email: String,
  age: Number,
});

const User = mongoose.model('User', userSchema);

async function createUser(name, email, age) {
  try {
    const newUser = new User({ name, email, age });
    await newUser.save();
    console.log('用户创建成功！');
  } catch (error) {
    console.error('创建用户失败：', error);
  }
}

createUser('John Doe', 'john@example.com', 25);
