There's some unfortunate version numbers there. That refers to version 3.6 of the third-party [importlib_metadata](https://pypi.org/project/importlib-metadata/) library, a later version of which was used for the ``importlib.metadata`` library included with Python 3.10. If you try to run `entry_points(group=""xarray.backends"")` on Python 3.9 it fails with a TypeError.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1215082284

Based on a change I made for plugins in that project, I think that changing

to

```python
    @functools.lru_cache(maxsize=1)
    def list_engines():
        try:
            entrypoints = entry_points(group=""xarray.backends"")  # Python >= 3.10
        except TypeError:
            entrypoints = entry_points().get(""xarray.backends"", ())
        return build_engines(entrypoints)
```

will take care of this. Not tested as I don't have access to an older Python environment right now, but I can make a pull request later if this would be a suitable workaround and nobody else does so first.","{""total_count"": 2, ""+1"": 2, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1215082284
