Getting errors with website theme saving

I have checked both my node and node sass versions but am still getting the below message
throw new Error(errors.unsupportedEnvironment());

Error: Node Sass does not yet support your current environment: Linux 64-bit with Unsupported runtime (93)
For more information on which environments are supported please see:

Is there an easy way to fix otherwise I’m backing up and spending two days to rebuild again.
node -v reports

and ~/frappe-bench/apps/frappe$ yarn list --depth 0 | grep sass
├─ node-sass@4.14.1
├─ sass-graph@2.2.5
so it looks correct to my simple mind.
What Am I missing

There’s a good chance you have conflicting versions of node on your server, installed via different methods and callable at different paths. Generally speaking, you might try uninstalling your distro’s version via apt, but it can be tricky to fix this.
