Conflicting Peer Dependencies

Hi,

I am currently upgrading NestJS to version 8 as it is supposed to work now with MikroORM.

However, I am receiving the following issues after a clean npm install and running npm audit fix.

npm audit fix

As far as I would understand it, peer @nestjs/common@"^7.0.0||^8.0.0" from @mikro-orm/[email protected] would also include version 8.0.11 which I have installed (@nestjs/common)

Any idea on how to fix this so that it does not show up anymore?

Was running npm audit fix --legacy-peer-depsto resolve it for now.

This feels like you still have @nestjs/[email protected] installed in your project, I don't think it has anything to do with the ORM setup. Maybe try to wipe your node modules, remove lock file and reinstall.

This module is not dependent on nest directly (only as a peer dep), so this @nestjs/[email protected] needs to come from your own project.
