'graphql/template-strings' not found

I get this error when I upgrade from 3.1.1 to 4.0.0:

Failed to compile
./src/components/CurrentTemperature.js
  Line 1:1:  Definition for rule 'graphql/template-strings' was not found  graphql/template-strings

./src/components/CurrentTemperature.js starts with:

/* eslint-disable graphql/template-strings */

$ npm install
$ npm start

Looks like in v3+ of CRA, you need EXTEND_ESLINT=true env var set.
