Issue

Alright, now that I got through all of that. I'm trying to convert a capistrano deploy over to heroku. Updated ember-cli-rails, ran the heroku generator, set build packs, pushed to heroku.

I get this error:

remote:        > undefined postinstall /tmp/build_2fc013553dfb362c78bacfaf58530cdb
remote:        > ./bin/heroku_install
remote:        
remote:        sh: 1: ./bin/heroku_install: Permission denied

remote:        npm ERR! undefined postinstall: `./bin/heroku_install`
remote:        npm ERR! Exit status 126

Or, in other words, it's getting a permission denied on ./bin/heroku_install

I thought, well maybe it's an issue with permissions, but an ls -l returns:

ls -l ./bin/
total 16
-rwxrwxr-x 1 kayakyakr kayakyakr 129 Oct 11 19:04 bundle
-rwxrwxr-x 1 kayakyakr kayakyakr 157 Jan 24 10:30 heroku_install
-rwxrwxr-x 1 kayakyakr kayakyakr 146 Oct 11 19:04 rails
-rwxrwxr-x 1 kayakyakr kayakyakr  90 Oct 11 19:04 rake

So I determined this is an issue with passing permissions through git. I modified package.json to look like:

{
  "scripts": {
    "postinstall": [
      "chmod a+x bin/heroku_install",
      "./bin/heroku_install"
    ]
  },
  "devDependencies": {
    "bower": "*"
  },
  "cacheDirectories": [
    "home/node_modules",
    "home/bower_components",
    "node_modules"
  ]
}

which forced the permission change on postdeploy itself and it worked. So that'd be my suggestion to deal with this issue hitting various people.

@kayakyakr thanks for opening this issue!

I've created #512.

Could you take a look at it and modify your application's package.json to us sh instead of ./, then report back here with the results?

That seems to work as well, Sean. Cleaner an implementation, too.
