ImportError：无法从“集合”导入名称“MutableMapping”

Question

我已使用 pip 在我的 alpine Docker 映像上安装了 AWS CLI Python 3.9.0a1。安装很顺利。当我运行该aws命令时，出现以下错误。

aws
Traceback (most recent call last):
  File "/usr/local/bin/aws", line 27, in <module>
    sys.exit(main())
  File "/usr/local/bin/aws", line 23, in main
    return awscli.clidriver.main()
  File "/usr/local/lib/python3.9/site-packages/awscli/clidriver.py", line 68, in main
    driver = create_clidriver()

    load_plugins(session.full_config.get('plugins', {}),

    modules = _import_plugins(plugin_mapping)
  File "/usr/local/lib/python3.9/site-packages/awscli/plugin.py", line 61, in _import_plugins
    module = __import__(path, fromlist=[module])

    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

我需要安装任何其他模块来修复此错误消息吗？

Answer 1

collections.MutableMapping自 Python 3.3 起已弃用，并自 Python 3.9 起正式删除。

文档摘录：

自版本 3.3 起已弃用，将在版本 3.9 中删除：将 集合抽象基类移至collections.abc模块。

您可以等待 Python 3.9 兼容版本的awscli发布，或者暂时自行修补aws脚本（在您的 下）：/usr/local/bin

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