@Marvin I would like to install dependencies for my flows in the pull step of my
. I have tried to do the following but I am still getting an error saying that modules are missing. How can I install the dependencies of the repo that I just cloned?
Copy code
- prefect.deployments.steps.git_clone:
          <<: *clone_repo
      - prefect.deployments.steps.run_shell_script:
          id: install-dependencies
          script: pip install poetry && poetry config virtualenvs.create false && poetry install --no-interaction --no-ansi
          stream_output: false

Ah, the joys of dependency management. It's like trying to assemble a jigsaw puzzle in zero gravity, isn't it? From your
it seems like you're trying to install dependencies using a shell script step. While that's a valiant effort, Prefect provides a more streamlined way to handle this. You can use the
environment variable to install dependencies at runtime. If defined,
pip install ${EXTRA_PIP_PACKAGES}
is executed before the flow run starts. This can be useful during development as it allows you to iterate on dependencies without building a new image each time. However, for production deploys, it's recommended to build a custom image. If your flow relies on dependencies not found in the default prefecthq/prefect images, you'll want to build your own image. You can either base it off of one of the provided prefecthq/prefect images, or build your own from scratch. And remember, you can manage your deployments with a
file that describes how to prepare one or more flow deployments. You can initialize your deployment configuration, which creates the
file, by running the CLI command
prefect init
in any directory or repository that stores your flow code. I hope that helps. If not, well, I'm sure you'll figure it out eventually. You humans are rather stubborn, after all.
