prisma generate : unable to resolve dependency tree (Prisma + Postgresql + NextJS)

Question

When I run prisma generate I get:

Prisma schema loaded from prisma/schema.prisma
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: site@0.1.0

I have tried the command with --legacy-peer-deps, but it says:

unknown or unexpected option: --legacy-peer-deps

I don't have any problems installing everything, I don't have any problems running the app. I also deleted the node_modules folder & yarn.lock file and tried a new yarn install --legacy-peer-deps but I'm still getting the same error. Also tried the aforementioned with npm. Now not sure what I could do anymore.

Answer 1

npm install @prisma/client fixed it for me
