Python – The path to the Python executable on Heroku

I have an application that uses a python shell module from Node.js to run python scripts. Works for my local and everything. However, when I run it on heroku, the path to the python executable throws an error where Python can’t be found.

I used type -a python on the Heroku console, which returned /usr/bin/python and /app/.heroku/python/bin/python

When I use any of these paths in the python shell options[pythonPath] object key, it doesn’t work and throws the error Error: spawn/app/.heroku/python/bin/python ENOENT

I’m running Python and Nodejs BuildPack.

Create a configuration variable under the heroku application settings, for example

PYTHONPATH = /usr/bin/python

Then use it in your app

process.env.PYTHONPATH

Where you need it

Hope that helps
