Heroku cannot find local npm package

Question

I have a local npm package included in my repo (I don't include the whole node_modules into my repo due to its over 200mb size, only specific package that I had to modify to suit my needs).

In package.json, local package declaration looks like this:

dependencies : { 
  local_package: "./my_local_package"
  ...
}

the error I got

 npm ERR! enoent ENOENT: no such file or directory, open 
 '/app/tmp/cache/my_local_package'

I'm not sure if /app/tmp/cache is the place where my repo resides and if it's not to what should I change it.

node v4.2.1, npm v2.14.7

According to npm documentation for local paths, you should define it this way:

"dependencies" : { 
  "local_package": "file:./my_local_package"
  ...
}
