node.js - Mongoose nodejs "Unknown modifier: $pushAll"

Question

你好，我正在学习这门类(class)，但我似乎无法解决我的问题，我明白了 { "名称": "MongoError", "message": "未知修饰符:$pushAll", “司机”:是的， “指数”:0， “代码”:9， "errmsg": "未知修饰符:$pushAll" 当我尝试创建新用户时。我查了一下，上面说太添加了 { usePushEach:真 }); 我做的我的 Mongoose 模式设置，但它仍然出错，我似乎无法修复它这里是代码

const mongoose = require("mongoose");
const validator = require("validator");
const jwt = require("jsonwebtoken");

var UserSchema = new mongoose.Schema({

  email: {
    require: true,
    type: String,
    minlength: 1,
    trim: true,
    unique: true,
    validate: {
      validator: validator.isEmail,
      message: `{VALUE} is not a valid email`
    }
  },
  password: {
    type: String,
    require: true,
    minlength: 6
  },
  tokens: [{
    access: {type: String, require: true},
    token: {type: String, require: true}
  }]
},{
  usePushEach: true
});

UserSchema.methods.generateAuthToken = function() {
  var user = this;
  var access = "auth";
  var token = jwt.sign({_id: user._id.toHexString(), access}, "abc123").toString();
  // user = user.concat({access, token})
  // console.log(user)
  user.tokens.push({access, token})

  return user.save().then(() => {
      return token
  })
};

var User = mongoose.model("User",  UserSchema);


module.exports = {User};

查看mongodb official documentation $pushAll 自 v2.4 以来已被弃用。

在最新的 mongodb 版本 (3.6) $pushAll 不再存在。

Use the $push operator with $each instead.

如果想强制使用$pushAll，this thread中给出了解决方案

问题的真正答案是:

@SkylarLopez hm... I would look at your version of mongoDb and mongoose. See if they match, maybe you have an unappropriate mongoose version that use $pushAll in it .save method
