What happened?

I installed xarray 0.21.0 in a fresh venv and tried to import, but that raised the following exception: Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/venv/lib/python3.8/site-packages/xarray/__init__.py", line 1, in <module> from . import testing, tutorial, ufuncs File "/tmp/venv/lib/python3.8/site-packages/xarray/testing.py", line 8, in <module> from xarray.core import duck_array_ops, formatting, utils File "/tmp/venv/lib/python3.8/site-packages/xarray/core/duck_array_ops.py", line 24, in <module> from . import dask_array_compat, dask_array_ops, dtypes, npcompat, nputils File "/tmp/venv/lib/python3.8/site-packages/xarray/core/dask_array_compat.py", line 4, in <module> from packaging.version import Version ModuleNotFoundError: No module named 'packaging'

What did you expect to happen?

That the import would go fine

Minimal Complete Verifiable Example

python python3.8 -m venv /tmp/venv . /tmp/venv/bin/activate pip install xarray==0.21.0 python -c "import xarray" ```

Relevant log output

python Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/venv/lib/python3.8/site-packages/xarray/__init__.py", line 1, in <module> from . import testing, tutorial, ufuncs File "/tmp/venv/lib/python3.8/site-packages/xarray/testing.py", line 8, in <module> from xarray.core import duck_array_ops, formatting, utils File "/tmp/venv/lib/python3.8/site-packages/xarray/core/duck_array_ops.py", line 24, in <module> from . import dask_array_compat, dask_array_ops, dtypes, npcompat, nputils File "/tmp/venv/lib/python3.8/site-packages/xarray/core/dask_array_compat.py", line 4, in <module> from packaging.version import Version ModuleNotFoundError: No module named 'packaging' ```

Anything else we need to know?

No response

Environment

Can't import xarray to generate this output, but relevant versions are python==3.8.5 pip==20.1.1
