Heroku: run Rails application using Python script on the same instance

I have a Python script in the directory of /app/bin

my Rails application that contains a file requirements.txt

that includes all the dependencies it relies on.

How do I get it to run on the same Heroku instance that the Rails app is currently running on (the Rails app sometimes calls a python script).

Here's what I've tried so far:

• Place the file requirements.txt
  
  in a directory /
  
  . Failed to install any python dependencies.
• It is chased heroku run bash
  
  and then executed pip install -r requirements.txt
  
  . Received a message pip command not found
  
  .
• Tried installing pip via bash interface using sudo python get-pip.py
  
  after curl
  
  with script as suggested on pipe install site . Doesn't work - unsurprisingly they don't support commands sudo
  
  in the instance.

I know Heroku should support pip

out of the box, but it doesn't do anything with the file requirements.txt

once the app is detected Ruby

.
