can't push ember cli app to heroku due to broccoli-sass and node-sass

Question

I've been trying to deploy to Heroku and it keeps throwing me an error. Apparently node 0.12 was not compatible with node-sass so I updated to node-sass 2.0.1 but it still doesn't work. I'm using ember cli 0.1.15

Module did not self-register.

Answer 1

The issue is happening because Heroku is using the last version of nodejs 0.12.0 which is incompatible with node-sass < 2.0.1 which is being use by broccoli-sass , you updated your local version of node-sass but broccoli-sass is still using the old version of node-sass There are some pull requests on broccoli-sass to fix that issue

Meanwhile you can modify your package.json

from

  "engines": {
    "node": ">= 0.10.0"
  }

to

  "engines": {
    "node": "0.10.x"
  }
