What happened:

I am pip installing xarray version 0.19.0 on python 3.9.7 and am getting the following error when trying to import xarray

``` import xarray as xr /usr/local/lib/python3.9/site-packages/xarray/init.py:3: in <module> from . import testing, tutorial, ufuncs /usr/local/lib/python3.9/site-packages/xarray/testing.py:8: in <module> from xarray.core import duck_array_ops, formatting, utils /usr/local/lib/python3.9/site-packages/xarray/core/duck_array_ops.py:15: in <module> from . import dask_array_compat, dask_array_ops, dtypes, npcompat, nputils /usr/local/lib/python3.9/site-packages/xarray/core/dask_array_compat.py:5: in <module> from .pycompat import dask_version /usr/local/lib/python3.9/site-packages/xarray/core/pycompat.py:55: in <module> dsk = DuckArrayModule("dask") /usr/local/lib/python3.9/site-packages/xarray/core/pycompat.py:22: in init duck_array_version = LooseVersion(duck_array_module.version) E AttributeError: module 'dask' has no attribute 'version'

```

What you expected to happen:

Doing pip install "xarray[complete]" fixes the issue. However, I don't want to install dask or the other optional packages as I want to reduce dependencies in my project.

Minimal Complete Verifiable Example:

python import xarray as xr # :)

Anything else we need to know?:

Thanks
