Installing Dagster

To follow the steps in this guide, you'll need:

  • To install Python 3.9 or higher. Python 3.12 is recommended.
  • To install pip, a Python package installer

Setting up a virtual environment​

After installing Python, it's recommended that you set up a virtual environment. This will isolate your Dagster project from the rest of your system and make it easier to manage dependencies.

There are many ways to do this, but this guide will use venv as it doesn't require additional dependencies.

python -m venv venv
source venv/bin/activate
tip

Looking for something more powerful than venv? Try pyenv or pyenv-virtualenv, which can help you manage multiple versions of Python on a single machine. Learn more in the pyenv GitHub repository.

Installing Dagster​

To install Dagster in your virtual environment, open your terminal and run the following command:

pip install dagster dagster-webserver

This command will install the core Dagster library and the webserver, which is used to serve the Dagster UI.

Verifying installation​

To verify that Dagster is installed correctly, run the following command:

dagster --version

The version numbers of Dagster should be printed in the terminal:

> dagster --version
dagster, version 1.8.4
