## I’m getting an error about greenlet not being installed when I try to use asyncio

The `greenlet` dependency is not install by default in the 2.1 series. To install including `greenlet`, you need to add the `asyncio` setuptools extra to the `pip install` command:

    pip install sqlalchemy[asyncio]

For more background, see Asyncio Platform Installation Notes.
