Yarn - Node Sass does not yet support my current environment

I'm using OSX latest version(10.14.4 (18E226)) and node 12.

While using node-sass 4.11, I had g++ error(../src/create_string.cpp:17:25: error: no matching constructor for initialization of 'v8::String::Utf8Value') while trying npm install, npm rebuild(link) which did not work.

I solved this by updating node-sass to 4.12(npm install node-sass), as the github issue on the node-sass says that support for node 12 is implemented in 4.12 version.

this is what worked for me. Downgrade your node version to 10.16.0 node 12 still has some issues
