If you're using a shell other than bash, type:Ĭonda init (Supported shells include: fish, tcsh, xonsh, zsh)Ĭlose and open the terminal.
Press enter until it asks for "yes" or "no", then type "yes" to accept the terms of use. Sudo chmod +x Miniconda3-latest-Linux-x86_64.sh Conda lets you manage different Python versions easily with virtual environments. If your app originally had multiple buildpacks set, you will need to add them in the same order as they were listed in heroku buildpacks previously.Consider installing Python with Anaconda or Miniconda (I recommend Miniconda). To do this, first clear the existing buildpacks set on the app, using: $ heroku buildpacks:clearĪnd then add the Python buildpack like so: $ heroku buildpacks:add heroku/pythonįinally check that the configured buildpacks are correct: $ heroku buildpacks If you see a GitHub URL such as the one above (or one that is pinned to a custom branch or tag), then it’s recommended that you instead switch to heroku/python, which is the curated stable buildpack registry release. To check which buildpack(s) are configured on your app, use the heroku buildpacks CLI command: $ heroku buildpacks So using it will improve build performance compared to GitHub URLs.įor more information see Buildpack References.
The stable heroku/python buildpack release is also pre-installed in the build environment, Not work, and you won’t benefit from future bug fixes or improvements made to the buildpack. (rather than pinning to a tag/branch or using a fork), otherwise some documented features may python-3.7.16 (available on the Heroku-20 stack only)įor best results it’s recommended that you are using the latest stable version of the buildpack.python-3.8.16 (available on the Heroku-20 stack only).python-3.9.16 (available on all stacks).python-3.10.11 (available on all stacks).python-3.11.3 (available on all stacks recommended).
You can also specify a different supported Python version. When a deployed application is recognized as a Python application, you’ll see this in the build output: $ git push heroku masterīy default, newly created Python apps use the python-3.11.3 runtime. Heroku automatically recognizes your app as a Python app if it includes a requirements.txt, setup.py or Pipfile file in its root directory. Heroku supports all popular web frameworks for Python (Django, Flask, and so on).įor a deployment tutorial that uses a sample Django app, see Getting Started on Heroku with Python.
