I'm getting an error about greenlet not being installed when I try to use asyncio
----------------------------------------------------------------------------------
The ``greenlet`` dependency does not install by default for CPU architectures
for which ``greenlet`` does not supply a `pre-built binary wheel <https://pypi.org/project/greenlet/#files>`_.
To install including ``greenlet``,
add the ``asyncio`` `setuptools extra <https://packaging.python.org/en/latest/tutorials/installing-packages/#installing-setuptools-extras>`_
to the ``pip install`` command:
.. sourcecode:: text
pip install sqlalchemy[asyncio]
For more background, see :ref:`asyncio_install`.
