Node-sass causing problems when trying to run "npm run dev"

[bonniesimon]

When I run npm run dev, I get a electron app with directory listing (similar to this). I digged into the issue a bit and found out that this had to do with node-sass.

This is the error on the console

Error: Node Sass does not yet support your current environment: OS X 64-bit with Unsupported runtime (93)

How can I fix this?
