Ember-Cli app failing to build

[noskiboots]

I am trying to deploy my app to Heroku using this buildpack. It has been working successfully for a while until about 2 weeks ago. I am getting the follow error output when attempting to deploy using "git push heroku master".

I have also switched my repo from github to bitbucket recently.

TLDR; change your node engine in your package.json to the version of node that’s working for you locally.

Experiencing this as well with ember-cli@2.13.2 and the issue turned out the be how engines.node is getting defined by default in the newer ember-cli releases like this:

{
  "engines": {
    "node": "> 4"
  }
}

That was causing Heroku to download v8.0.0 of node which is likely unstable and ended up causing dependencies, required for the ember build process, to not get successfully installed.

I fixed this by setting my engine to an LTS release of node, one of which at this time is "6.10.3".

I would concur based on similar reports that this is likely a Node 8 issue and would also recommend using the most recent LTS. If that doesn't fix this please re-open with any additional details that may be helpful.
