Hi there, I'm using route handler serverless functions and have installed an npm package 'sharp' to run some image optimisations. Everything is working locally but after deploying to vercel the functions fail with Error: Cannot find module 'sharp' .

I've tried reinstalling node_modules with yarn and removing the lock file. None of this has helped. Any help is appreciated thank you.

It turns out that the package has native dependencies that need to be specifically installed.
Does anyone know how to do this?
