这里有一些关于排序的不错的答案，这里有一些关于mongoose Async/Await的很好的官方文档

您应该使用.exec()和await来进行更好的堆栈跟踪，排序可以采用以下值:asc，desc，ascending，descending，1和-1。

try {
    let properties = await Property.find(query).sort({"minimumPrice": -1}).exec() 
} catch (err) {
   console.log(err)
}

这都是假设您的查询是正确的，并且正在检索要排序的文档。

更新

我看了你的整个情况，用你提供的东西创建了一个测试。

const mongoose = require("mongoose");
var Schema = mongoose.Schema;
var propertySchema = new Schema({
  name: String,
  minimumPrice: Number
});
var Property = mongoose.model('Property', propertySchema);

//Testing
(async function() {
  try {
    //connect to mongo
    await mongoose.connect('mongodb://localhost:27017/testing', { useNewUrlParser: true, useUnifiedTopology: true });

    //First, delete all properties
    await Property.deleteMany({}).exec();

    let properties = [];
    //Insert 5 properties
    for (var i = 1; i < 6; i++) {
      properties.push({ name: "property" + i, minimumPrice: Math.round(Math.random() * 10000) });
    }

    //Insert all our random properties
    await Property.create(properties);

    console.log(properties);

    //Now, retrieve all our properties
    let sortedProperties = await Property.find({}).sort({ minimumPrice: -1 }).exec();

    console.log("sorted", sortedProperties);
  } catch (err) {
    console.log(err);
  }
})();

数据库输入:

[                                           
  { name: 'property1', minimumPrice: 3846 },
  { name: 'property2', minimumPrice: 7910 },
  { name: 'property3', minimumPrice: 7234 },
  { name: 'property4', minimumPrice: 4444 },
  { name: 'property5', minimumPrice: 6366 } 
]                                           

已排序输出:

[
  {
    name: 'property2',
    minimumPrice: 7910
  },
  {
    name: 'property3',
    minimumPrice: 7234
  },
  {
    name: 'property5',
    minimumPrice: 6366
  },
  {
    name: 'property4',
    minimumPrice: 4444,
  },
  {
    name: 'property1',
    minimumPrice: 3846
  }
]

您可以看到属性按顺序返回。 这让我假设，您已经将minimumPrice作为字符串插入了某个位置。
