npm script fails with "SyntaxError: Cannot use import statement outside a module" #419

I'm trying to run postcss on my Windows system with NodeJS 12.14. I'm consistently getting "SyntaxError: Cannot use import statement outside a module".

Here's the full output:

PS C:\Emr\Tools\bootstrap> node -v
v12.14.0

PS C:\Emr\Tools\bootstrap> postcss --config build/postcss.config.js --replace "dist/css/*.css" "!dist/css/*.min.css"
C:\Users\uluho\AppData\Roaming\npm\node_modules\postcss-cli\index.js:3
import fs from 'fs-extra'
^^^^^^

You need to use Node 12.17+ to support ESM modules without a flag, which postcss-cli uses.
