Heroku push fails to compile. Error points to node-sass. Possible dependency mismatch, log included

Question

Sorry if this has been asked/answered before. Similar questions I found over google either had open tickets, or people suggested downgrading dependencies. I am unclear as to why the build is failing, when it seems to be working properly on my local machine.

Thanks for any help you can provide!

Answer 1

I had exactly the same problem. Downgrading the node version from 4.1.1 to 0.12.2 fixes the problem for me.
