I am trying to build and run a project on an npx dev-server. My package.json file has "type":"module" inside the first {} as recommended here. When I run npm ci && npm run build in terminal (MacOS Mojave), I get the following error message:
[!] SyntaxError: Unexpected token {

The debug logs give the following additonal error info:

When I try to run an npx server using npx @web/dev-server --root-dir static --app-index static/index.html, I get this error:
npm ERR! could not determine executable to run
I've tried updating npm through a number of methods:
npm rm -rf node_modules
npm install --legacy-peer-deps
but am still getting the same errors.
Any suggestions on where to start would be appreciated.
