I had same problem but didn't have to downgrade the node version. I just updated the package.json file node-sass entry to match my node version from the table on the github page. https://github.com/sass/node-sass/
I'm using node 14.15.3 so I put "node-sass": "^4.14.0" in dependencies, did another npm install, and it worked.
