Prevent sass build error on master

Investigate how to prevent error reaching master

/usr/src/app/node_modules/node-sass/lib/binding.js:13
      throw new Error(errors.unsupportedEnvironment());
      ^
Error: Node Sass does not yet support your current environment: Linux/musl 64-bit with Unsupported runtime (88)

Fixed the last time with !172 (merged)
