Trying to deploy on Heroku

I followed the steps religiously at https://github.com/thoughtbot/ember-cli-rails/ but unable to deploy even a sample app.

$ rails new reg2
$ cd reg2

At that point, I started following step by step, starting with adding the gem 'ember-cli-rails.'

I also created a heroku app

$ heroku login
$ heroku create

However, I am unable to push to Heroku. I get this error stack:

reg2 $ git push heroku master

These are some of the fixes I have tried but failed with:
* In ./package.json, modify sh bin/heroku_install to ./bin/heroku_install
* In https://github.com/seanpdoyle/ember-cli-rails-heroku-example, he suggests running generator using rails g ember-cli:heroku but the ember-cli:heroku command is not even recognized; terminal recommends using ember:heroku so that was a dead end as well.

I built the heroku webpacks as such:

$ heroku buildpacks:clear
$ heroku buildpacks:add --index 1 https://github.com/heroku/heroku-buildpack-nodejs
$ heroku buildpacks:add --index 2 https://github.com/heroku/heroku-buildpack-ruby
$ heroku config:set NPM_CONFIG_PRODUCTION=false
$ heroku config:unset SKIP_EMBER

Here is what my reg2/package.json (root package.json) looks like:

{
  "scripts": {
    "postinstall": "sh bin/heroku_install"
  },
  "dependencies": {
    "bower": "*"
  },
  "cacheDirectories": [
    "frontend/node_modules",
    "frontend/bower_components",
    "node_modules"
  ]
}

Been banging my head against this for a couple days now; would REALLY appreciate your help!

[hoopsphere]

Would appreciate if someone could help me out!

[dirtyhenry]

Not an expert but you're using npm version 5.0.3 when you develop and Heroku says Using default npm version: 3.10.10.

In addition, Heroku says:

remote:     Some possible problems:
remote:
remote:        - Node version not specified in package.json
remote:        https://devcenter.heroku.com/articles/nodejs-support#specifying-a-node-js-version

Have you followed this tip?

[dirtyhenry]

Also, can you share the content of sh bin/heroku_install?

[seanpdoyle]

remote:        bower                           ENOENT No bower.json present

Seems to be the problematic line of logging output.

#532 added support for skipping bower install when bower.json is absent.

Unfortunately, that commit did not modify the generated heroku_install.sh script.

Does your project have a bower.json file?

If not, could you try removing any bower-related lines from your bin/heroku_install.sh file?

[seanpdoyle]

@hoopsphere was this issue closed intentionally?

Did removing the bower-related lines resolve your build errors?

[gohdaniel15]

Hey @seanpdoyle. Just deployed my ember-cli-app today and ran into the same issues. I had to go in there and remove the bower-related lines.

Wondering if something could be done about this (eg; for a different heroku_install.sh template to be run if a bower.json file isn't detected in the app || some documentation).

[getaclue00]

not sure if its relevant but I just uploaded a new project to heroku and it was failing @ running the heroku_install.sh file. I connected to the box via heroku run bash and then checked the contents of /bin and the file is not there. Check contents of my .gitignore and /bin isnt ignored. Wondering why the file isnt getting there.

[seanpdoyle]

@GetAClue did you run the ember:heroku generator?

There are some issues with the way Heroku setup currently works. We're actively working Heroku setup to remove the bash script and no longer rely on NPM's postinstall hook.

[getaclue00]

@seanpdoyle I did -- also ended up just rewriting the postinstall script using inline with the commands that were in that file... and it ran fine. So that's fine for now.

I'm not sure if my problem (I tried to reach out to you on ember's Slack) is related to this or something else. My ember's image assets are not being moved to public folder from the /tmp. Tried to follow #30 but didn't see a solution that worked for me. Currently reading your code-base to see where the cp function is being ran to see why my images are not being carried over.

(and I'm not using a cdn... just wanting it served via Rails I should add)

Just thought I'd comment that things seem to be working OK now with the latest release?

heroku deploy is working well for us in production with the new gem release, with various combinations of yarn/npm, bower/no-bower, and the bin/heroku_install script deleted.

Images are working fine for us too with ember-cli and rootURL settings.
