I'm getting the following error:

  File "/home/ron/rzg2l_bsp_v1.3/poky/bitbake/lib/bb/compat.py", line 7, in <module>
    from collections import MutableMapping, KeysView, ValuesView, ItemsView, OrderedDict
ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)

and Googling revealed that flask has to be >=2.0, so I did

$ sudo pacman -Syu python-flask

which installed version (2.0.2-3)

which did not resolve the issue. Further searching revealed that babelfish needs to be upgraded too, so I did:

$ python3.10 -m pip install babelfish -U

which showed me:

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: babelfish in /home/ron/.local/lib/python3.10/site-packages (0.6.0)

but I'm still getting the same error. Can anyone tell what else I'm missing?

You need to import collection.abc

Here the link to doc

>>> from collections import MutableMapping
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)
>>> from collections.abc import MutableMapping

Deprecated since version 3.3, will be removed in version 3.10: Moved Collections Abstract Base Classes to the collections.abc module. For backwards compatibility, they continue to be visible in this module through Python 3.9.

Ref. https://docs.python.org/3.9/library/collections.html

If you have more than one interpreter, use:

import sys

if sys.version_info[:2] >= (3, 8):
    from collections.abc import MutableMapping
else:
    from collections import MutableMapping

The direct import has been deprecated since Python 3.3 and will stop working in Python 3.9. You need to import using

from collections.abc import MutableMapping

This is the deprication warning I got

DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3,and in 3.9 it will stop working
