below is the error message:

Error: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (83)

This happens at time of running npm install?

Then is likely a version mismatch of your node version and the project. Use nvm to manage node versions

Did u migrate something?

Or better: please tell command you ran and output?
