Hello @photex, welcome to Sonar Community and thank you for your post! 
We are aware that this notification is a bit noisy and causes frustration 
. The underlying problem will be tackled soon, once we start embedding the Node.js runtime inside SonarLint, so the users will not need to install it themselves.
In the meantime, I’ve created this ticket to allow “muting” the error notification via the “Don’t show again” action.
Please also note that in case you don’t want to analyze those files at all, including on SonarCloud, you can configure your project to exclude those files, and the config will also be automatically applied in SonarLint in Connected Mode. 
Hope that helps,
Sophio
