Tough to say without a bit more information. My guess is you want to check if the version of node-sass (specified in the 'package.json' for Frappe) is compatible with the version of Node you have installed on your machine.

Compatibility matrix here.

From your error text, looks like you have Node v16.15. So you’ll need a ‘node-sass’ of v6.x


I can confirm that I had a lot of trouble with node-sass on node v16. My solution was to use nvm to switch back to node v14.
