An elm-pages app that was working ok with ‘npm start’ is now failing with:

…/node_modules/elm-pages/generator/src/cli.js:4
import * as build from “./build.js”;
^^^^^^

I wondering what has caused this.

My npm is 6.13.5, node is v12.14.1
My elm is 0.19.1

Hoping this is simple to fix

Node.js 12 is very old. It got end-of-life 3 years ago.

Try Node.js 20 or later.

Yes - that must be it. I have another Mac with node.js 20 and on that Mac my code works.

Updated node to v23.6.1 on the failing Mac - all works now.

Something must have installed an earlier version of node globally.

Thanks
