I recently updated my dev machine (Macbook Pro) to macOS Big Sur version 11.1. After upgrading, I encountered this error after running `npm run dev` on one of my projects.  Here's a quick fix that worked for me.. Make sure you are using the LTS version of node. You can get it from [nodejs.org](https://nodejs.org/) (version 14.15.4 as of this writing). Run `npm rebuild node-sass --force` command. And you should be good to go!
