You can fix this by suppressing the output of npm overall, by setting the log level to silent in a couple ways:

On each npm run invocation:

npm run --silent 

Or globally by creating a .npmrc file(this file can be either in your project directory or your home folder) with the following:

loglevel=silent

A simple trick I've used to get around this issue on certain scripts like linting is to append || true at the end of such scripts. This will work without any npm config changes.

This will ensure that the script will always exit with a 0 status. This tricks npm into thinking the script succeed, hence hiding the ERR messages. If you want to be more explicit, you can append || exit 0 instead and it should achieve the same result.

{
  "scripts": {
    "lint": "jshint || true",
   }
