Deprecated module is not found

[lheyberger]

I'm facing the following issue when trying to follow the README and importing the checkout SDK with from checkout_sdk.checkout_sdk import CheckoutSdk:

<path>/checkout_sdk/payments/contexts/contexts.py", line 3, in <module>
    from deprecated import deprecated
ModuleNotFoundError: No module named 'deprecated'

The Deprecated module is mentioned in the requirements-dev.txt file but the use of this file is only documented when building from sources.

Environment

• Checkout SDK version: checkout-sdk==3.1.3
• Python version: Python 3.13.1
• Operating System and version: MacOS 15.3

Current behavior

Installing the sdk with pip install checkout-sdk raises a ModuleNotFoundError

Expected behavior

I would expect that executing pip install checkout-sdk installs all the mandatory dependencies.
