You need multiple buildpacksfor your app.
Run the following:
heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi
Then, add the following in a file called .buildpacks in your project's root directory:
https://github.com/heroku/heroku-buildpack-python.git
https://github.com/heroku/heroku-buildpack-nodejs.git
Alternatively, you can use heroku toolbelt commands (heroku buildpacks:set and heroku buildpacks:add) to configure your multiple buildpacks, as described here.
