I wanted to highlight a couple of environment variables added earlier this year which can give you greater control over your builds — both of which were created by community contributors!
First, we have
PYTHON_VERSION, contributed by GitHub user duckinator, who recognized the benefit of consistency and added a variable for setting a build’s Python runtime in the same way that you can with Ruby or Node.js.
Next, we have
yarn.lock file in your site’s base directory.
You can learn more about these variables and build dependency management in the docs:
Hooray for users helping users! It’s a joy and an honor to be a part of the community you all help create.
