I've just imported my Reactjs project to a new machine on Ubuntu and installed most dependencies with npm install successfully bar the following:
npm WARN optional Skipping failed optional dependency /react-scripts/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: [email protected]
npm WARN optional Skipping failed optional dependency /chokidar/fsevents:
npm WARN notsup Not compatible with your operating system or architecture: [email protected]
Trying to run the project with npm start fails with:
> [email protected] start /root/17-visit-booker-frontend
> react-scripts start
/root/17-visit-booker-frontend/node_modules/react-scripts/scripts/start.js:33

Attempting to run any npm script including npm run build all fails with the exact same error referencing the same lines in each file in the SyntaxError:

Running the same scripts on my original machine, a Mac, succeed.
I've tried re-installing node/npm which do not fix the issue. Is the supposedly optional dependency causing this to fail?
Any help is appreciated.
const { choosePort, createCompiler, prepareProxy, prepareUrls, } = require('react-dev-utils/WebpackDevServerUtils');where the only thing occupying line 33 isconst {and each comma-separated item is on a new line.npm run buildcauses it to complain with :/root/17-visit-booker-frontend/node_modules/react-scripts/scripts/build.js:60 ({ stats, previousFileSizes, warnings }) => {and points at the first occurrence of a curly brace.
