Notice that the library also need to be installed in RedisGears virtual env.
- Create a virtualenv to manage your python dependencies, and ensure it's active.
virtualenv -v venv
- Install pypoetry to manage your dependencies.
pip install poetry
- Install dependencies.
poetry install
tox runs all tests as its default target. Running tox by itself will run unit tests. Ensure you have a running redis, with the module loaded.
