I installed Prisma and I run npx primsa db push it pushed all tables to database successfully, after that I run npx prisma generate it tried to install @prisma/client and it fails with this error message:
error An unexpected error occurred: "EPERM: operation not permitted, unlink 'path_to_project\node_modules\prisma\query_engine-windows.dll.node'
I tried to remove node_modules and re-install all modules but it not worked.
I had to install @prisma/client manually with yarn add @prisma/client then run npx prisma generate it works perfectlly.
I had this same error type with a different package. In my case the thing that was causing the error was because it couldn't access the folder while the app was still running ie. from this issue https://github.com/yarnpkg/yarn/issues/2685
This was following npm cache clean --force not resolving it.
I had the same error but after installing Microsoft Visual C++ 2015 Redistributable it works fine now
