Step 2: Install dependencies

Let's create a python virtual environment for our source. You can do this by executing the following commands from the root of the Airbyte repository.

The command below assume that python points to a version of python >=3.9.0. On some systems, python points to a Python2 installation and python3 points to Python3. If this is the case on your machine, substitute the python commands with python3. The subsequent python invocations will use the virtual environment created for the connector.

cd ../../connectors/source-exchange-rates-tutorial
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

These steps create an initial python environment, and install the dependencies required to run an API Source connector.

Let's verify everything works as expected by running the Airbyte spec operation:

python spec

You should see an output similar to the one below:

{"type": "SPEC", "spec": {"documentationUrl": "", "connectionSpecification": {"$schema": "", "title": "Python Http Tutorial Spec", "type": "object", "required": ["TODO"], "additionalProperties": false, "properties": {"TODO: This schema defines the configuration required for the source. This usually involves metadata such as database and/or authentication information.": {"type": "string", "description": "describe me"}}}}}

This is a simple sanity check to make sure everything is wired up correctly. More details on the spec operation can be found in Basic Concepts and Defining Stream Schemas.

For now, note that the file is a convenience wrapper to help run the connector. Its invocation format is python <command> [args]. The module's generated contains more details on the supported commands.
