Heroku Build Failed: Node version not specified in package.json

https://dashboard.heroku.com/apps/label-sync/activity/builds/af659b46-553d-4a27-a51d-0292aa216dec

https://devcenter.heroku.com/articles/troubleshooting-node-deploys https://devcenter.heroku.com/articles/nodejs-support#specifying-a-node-js-version

Appears we've got to specify a Node.js version in package.json

[nelsonic]

Visiting the settings page for the app: https://dashboard.heroku.com/apps/label-sync/settings

We see that the specified Buildpack is:

https://github.com/heroku/heroku-buildpack-nodejs#v83

Released 5 Oct 2015: https://github.com/heroku/heroku-buildpack-nodejs/releases/tag/v83

We will need to upgrade this to the latest version of Node.js as part of #94 But for now I'm just trying to figure out what version of Node is being used (working) so that I can specify it in the package.json so we can deploy the label.description PR #93

Sadly the Heroku Buildpack release doesn't give us any info regarding the Node.js version.

The CHANGELOG.md doesn't give us any insight into what Node.js they were using: 🤦

Thankfully we can lookup what Node.js version was current back in October 2015: https://nodejs.org/en/download/releases

So I'm going to try specifying Node.js 4.1.1 released 2015-09-23.

adding the engines directive to package.json with Node.js 4.1.1:

https://github.com/dwyl/labels/blob/cedc14f5eaee893642142f45dcdb4237983cb68f/package.json#L45-L47

appears to have worked when I pushed the branch to Heroku:

git push heroku add-node-version-to-packagejson-issue-95:master
