The app works fine however I am not sure of future impacts of the error encountered while installing fsevents. Unclear if this can be safely ignored or node or npm version must be downgraded. The issue can be re-created at will.

Reproducible Demo

Just run any of the commands below with the version of npm and node shown above-

npx create-react-app my-app
npm init react-app my-app

I am running Node v10.15.0 and npm v6.4.0, and I am getting the same error.

However, unlike annjawn, I can’t run the app at all.

This is almost certainly because you’re running Node 11. Compilation of native modules with node-pre-gyp breaks frequently on new versions of Node. Try using Node 10 instead.
