如何使用mongoose从mongodb模式中删除索引？

npm install mongoose mongodb

const mongoose = require('mongoose');
const { MongoClient } = require('mongodb');

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

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

const Model = mongoose.model('Model', schema);

Model.collection.dropIndexes((err, result) => {
  if (err) {
    console.error('删除索引失败:', err);
  } else {
    console.log('索引删除成功:', result);
  }
});
