typegoose使用报错

Question

koa项目引入typegoose后运行报错：

具体报错内容：

6:54:09 PM - File change detected. Starting incremental compilation...

node_modules/@typegoose/typegoose/lib/hooks.d.ts(8,41): error TS2707: Generic type 'Query<ResultType, DocType, THelpers, RawDocType>' requires between 2 and 4 type arguments.

6:54:09 PM - Found 1 error. Watching for file changes.

泛型类型“Query<ResultType, DocType, THelpers, RawDocType>”需要介于 2 和 4 类型参数之间。

model.js:

import { getModelForClass, prop } from '@typegoose/typegoose'

class StoryClass {
  @prop()
  public id?: string;

  @prop()
  public name?: string;
}

const StoryModel = getModelForClass(StoryClass)

export default StoryModel

依赖版本：

"dependencies": {
    "@typegoose/typegoose": "^7.6.1",
    "axios": "^0.21.1",
    "dayjs": "^1.10.5",
    "koa": "^2.13.1",
    "koa-router": "^10.0.0",
    "mongoose": "^5.13.1"
  },
  "devDependencies": {
    "@types/koa": "^2.13.1",
    "@types/koa-router": "^7.4.1",
    "@types/mongoose": "^5.11.97",
    "@types/node": "^14.14.37",
    "ts-node": "^9.1.1",
    "tsc-watch": "^4.4.0",
    "typescript": "^4.2.4"
  },

有大佬帮忙看看什么问题吗？

Answer 1

应该是你安装的@types/mongoose和mongoose自带的.d.ts文件有冲突，mongoose在5.10.18开始自带.d.ts文件了。
