Unsupported platform for [email protected] installation issue

Question

I've been trying to deploy my application to vercel for a while now and have been reading through lots of posts here on stackoverflow with the the same/similar fsevents issue. Despite everything I keep getting the same errors posted below.

things I've tried:

• uninstall node_modules & package-lock.json, then running: npm i -f
• adding "optionalDependencies": {"fsevents": "^2.3.2"}, then npm i -f
• installing with no fsevents in package.json
• ... and many other attempts

Screen shot of what always happens in my deploys

I'm not super familiar with that what/why of the whole fsevents/chokidar packages, but it seems like it's needed for my MacOS after what I've been reading and I'd really appreciate some ideas for resolving this.

lots of people complaining about this going back years.

sometimes the fix is upgrading to newer npm. (running npm 7.7 and still had it)

often the fix is just :

npm install -f

so forcing it worked just fine here.
