没有重载与使用 typescript 和 express 运行 mongoose 的调用相匹配

Question

我收到 useNewUrlParser、useUnifiedTopology、useCreateIndex 的以下错误：

No overload matches this call.
  Overload 1 of 3, '(uri: string, callback: CallbackWithoutResult): void', gave the following error.
    Argument of type '{ useNewUrlParser: boolean; useUnifiedTopology: boolean; useCreateIndex: boolean; }' is not assignable to parameter of type 'CallbackWithoutResult'.
      Object literal may only specify known properties, and 'useNewUrlParser' does not exist in type 'CallbackWithoutResult'.
  Overload 2 of 3, '(uri: string, options?: ConnectOptions | undefined): Promise<typeof import("mongoose")>', gave the following error.
    Argument of type '{ useNewUrlParser: boolean; useUnifiedTopology: boolean; useCreateIndex: boolean; }' is not assignable to parameter of type 'ConnectOptions'.
      Object literal may only specify known properties, and 'useNewUrlParser' does not exist in type 'ConnectOptions'.

索引.ts

import express from 'express'
import { errorHandler } from './middleware/error-handler';
import router from './router'
import mongoose from 'mongoose'

const app = express()

app.use(express.json())
app.use('/api/users', router)
app.use(errorHandler)

const start = async () => {
  try {
    await mongoose.connect("mongodb://auth-mongo-srv:27017/auth", {
      useNewUrlParser: true,    // error here
      useUnifiedTopology: true,
      useCreateIndex: true,
    });
    console.log("Connected to MongoDb");
  } catch (err) {
    console.error(err);
  }
};

const PORT = 3000
app.listen(PORT, () => {
    console.log("working on port ",PORT)
})

start()

tsconfig.json

{
  "compilerOptions": {
"target": "es6",
"module": "commonjs", 
"esModuleInterop": true, 
"forceConsistentCasingInFileNames": true,
"strict": true, 
"skipLibCheck": true
 }
}

我在 package.json 中安装了 mongoose 6.02，如果有任何帮助，我将从 dockerhub 获取 mongo 并在集群 pod 中运行。

任何帮助或建议表示赞赏。

Answer 1

只需删除这些选项即可，不再需要它们

https://mongoosejs.com/docs/migration_to_6.html#the-aspromise-method-for-connections

useNewUrlParser、useUnifiedTopology、useFindAndModify和useCreateIndex不再受支持的选项。Mongoose 6 的行为始终表现为useNewUrlParser、useUnifiedTopology、 和useCreateIndex为 true，而useFindAndModify为 false。请从您的代码中删除这些选项。

Answer 2

6.0.2版本的mongoose的ConnectOptions不包括useNewUrlParser、useUnifiedTopology、useCreateIndex。但是，6.0.2 的 mongoose 文档仍然显示这些选项有效，如果没有这些选项，mongoose 将引发拓扑错误。

将 mongoose 降级到版本 5.13.8，现在它可以正常工作。
