ImportError: cannot import name 'MutableMapping' from 'collections' [duplicate]

Question

I have installed the AWS CLI using pip on my Python 3.9.0a1 alpine Docker image. Installation went fine. When I run the aws command, I'm getting the following error.

aws
Traceback (most recent call last):
  File "/usr/local/bin/aws", line 27, in <module>
    sys.exit(main())

    from collections import MutableMapping
ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/local/lib/python3.9/collections/__init__.py)



python --version
Python 3.9.0a1

Do I need to install any other module to fix this error message?

Answer 1

collections.MutableMapping has been deprecated since Python 3.3, and was officially removed since Python 3.9.

Excerpt from the documentation:

Deprecated since version 3.3, will be removed in version 3.9: Moved Collections Abstract Base Classes to the collections.abc module.

You can either wait for a Python 3.9-compatible version of awscli to be released, or patch the aws script (under your /usr/local/bin) yourself like this for the time being:

...
import collections
from collections import abc
collections.MutableMapping = abc.MutableMapping
import awscli.clidriver

Answer 2

As said in other answers, the issue is the deprecation of some aliases from collections.abc into collections from python 3.10.

If you can't modify the importations in your scripts because of a third-party import, as a temporary workaround you can do the aliases manually before importing the problematic third-party lib. See the example below for the importation of hyper library for example, which causes similar issues as yours.

import collections

collections.Iterable = collections.abc.Iterable
collections.Mapping = collections.abc.Mapping
collections.MutableSet = collections.abc.MutableSet
collections.MutableMapping = collections.abc.MutableMapping
