I had installed a sage9 theme a few weeks ago. I came back to it today and yarn run build is showing an error:
Module build failed: ModuleBuildError: Module build failed: Error: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (72)
A bit of time searching Google led me to delete node_modules and run yarn again, which is now giving even more errors:
/Users/designlobby/.node-gyp/12.3.1/include/node/v8.h:3002:5: note: candidate constructor not viable: no known conversion from 'v8::Local<v8::Value>' to 'const v8::String::Utf8Value' for 1st argument
Utf8Value(const Utf8Value&) = delete;

I tried installing a fresh sage9 theme, but the same errors came up again when I ran yarn.
I’m not quite sure what to do now… Any ideas?
