| # INSTALL / BUILD instructions for Apache Airflow |
| |
| This ia a generic installation method that requires a number of dependencies to be installed. |
| |
| Depending on your system you might need different prerequisites, but the following |
| systems/prerequisites are known to work: |
| |
| Linux (Debian Buster and Linux Mint Tricia): |
| |
| sudo apt install build-essentials python3.6-dev python3.7-dev python-dev openssl \ |
| sqlite sqlite-dev default-libmysqlclient-dev libmysqld-dev postgresq |
| |
| MacOS (Mojave/Catalina): |
| |
| brew install sqlite mysql postgresql |
| |
| # [required] fetch the tarball and untar the source move into the directory that was untarred. |
| |
| # [optional] run Apache RAT (release audit tool) to validate license headers |
| # RAT docs here: https://creadur.apache.org/rat/. Requires Java and Apache Rat |
| java -jar apache-rat.jar -E ./.rat-excludes -d . |
| |
| # [optional] Airflow pulls in quite a lot of dependencies in order |
| # to connect to other services. You might want to test or run Airflow |
| # from a virtual env to make sure those dependencies are separated |
| # from your system wide versions |
| |
| python3 -m venv PATH_TO_YOUR_VENV |
| source PATH_TO_YOUR_VENV/bin/activate |
| |
| NOTE!! |
| |
| On November 2020, new version of PIP (20.3) has been released with a new, 2020 resolver. This resolver |
| does not yet work with Apache Airflow and might lead to errors in installation - depends on your choice |
| of extras. In order to install Airflow you need to either downgrade pip to version 20.2.4 |
| ``pip install --upgrade pip==20.2.4`` or, in case you use Pip 20.3, you need to add option |
| ``--use-deprecated legacy-resolver`` to your pip install command. |
| |
| # [required] building and installing by pip (preferred) |
| pip install . |
| |
| # or directly |
| python setup.py install |
| |
| # You can also install recommended version of the dependencies by using |
| # constraint-python<PYTHON_MAJOR_MINOR_VERSION>.txt files as constraint file. This is needed in case |
| # you have problems with installing the current requirements from PyPI. |
| # There are different constraint files for different python versions. For example" |
| |
| pip install . \ |
| --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-master/constraints-3.6.txt" |
| |
| |
| By default `pip install` in Airflow 2.0 installs only the provider packages that are needed by the extras and |
| install them as packages from PyPI rather than from local sources: |
| |
| |
| pip install . \ |
| --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-master/constraints-3.6.txt" |
| |
| |
| You can also install airflow in "editable mode" (with -e) flag and then provider packages are |
| available directly from the sources (and the provider packages installed from PyPI are UNINSTALLED in |
| order to avoid having providers in two places. And `provider.yaml` files are used to discover capabilities |
| of the providers which are part of the airflow source code. |
| |
| You can read more about `provider.yaml` and community-managed providers in |
| https://airflow.apache.org/docs/apache-airflow-providers/index.html for developing custom providers |
| and in ``CONTRIBUTING.rst`` for developing community maintained providers. |
| |
| This is useful if you want to develop providers: |
| |
| pip install -e . \ |
| --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-master/constraints-3.6.txt" |
| |
| You can als skip installing provider packages from PyPI by setting INSTALL_PROVIDERS_FROM_SOURCE to "true". |
| In this case Airflow will be installed in non-editable mode with all providers installed from the sources. |
| Additionally `provider.yaml` files will also be copied to providers folders which will make the providers |
| discoverable by Airflow even if they are not installed from packages in this case. |
| |
| INSTALL_PROVIDERS_FROM_SOURCES="true" pip install . \ |
| --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-master/constraints-3.6.txt" |
| |
| Airflow can be installed with extras to install some additional features (for example 'async' or 'doc' or |
| to install automatically providers and all dependencies needed by that provider: |
| |
| pip install .[async,google,amazon] \ |
| --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-master/constraints-3.6.txt" |
