[ng] Module build failed (from ./node_modules/sass-loader/lib/loader.js):
[ng] Error: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (93)
This is usually because of the conflicts with node-sass and node. You might updated your node version accidentally.
Check you node version,
node -vthen, note down your node-sass version from package.json
After that, check the supported versions from https://github.com/sass/node-sass
Always be careful when updating NPM or NODE and that's my 2 cents 🙂
