Look like node-sass makes the problem
Any idea?

@eliavmaman maintenance on the project has stalled. if you're able to pick up maintenance on the project, I'll be happy to add you as a contributor

@eliavmaman did you try removing the '>' from package.json ->
I changed it from:
"engines": {
"node": ">=6.10.0",
"npm": ">=3.10.8"
},
to:
"engines": {
"node": "6.10.0",
"npm": "3.10.8"
},
and it started building for me. See this for more info -> #1928

Lots of problems seem to stem from gulp dependencies. I removed gulp dependencies and instead use just "start: "npm start" for heroku. Setting the node environment to development worked like a charm.
