mongoose Namespace has no exported member 'OptionalId'

Question

I am getting this error while i run npm i.

../@types/mongoose/index.d.ts:191:17 - error TS2694: Namespace '"/Users/test-service/node_modules/@types/mongodb/index"' has no exported member 'OptionalId' ? mongodb.OptionalId & { _id: TId }>

I am using "@types/mongoose": "^5.5.32", "@types/mongodb": "~3.3.1". Can someone help me solving this problem. my tsc version is Version 3.8.3 .

Answer 1

I just solved the problem by running this command.

npm install --save @types/mongodb

Hope this can help you.

Answer 2

Why ?

my project node_modules like this,

• node_modules
  • @types/mongoose/@types/mongodb
  • @types/mongodb

@types/mongoose has @types/mongodb dependencie, and it has conflict with @types/mongodb.

How to Fix

Run this command at your node_modules directory:

$ rm -rf node_modules/@types/mongoose/node_modules/@types/mongodb

Done.

Hope to help someone.
