AWS CLI与Python 3.9.0a1错误`来自集合导入可变映射`

Question

我已经在我的Python 3.9.0a1alpine docker映像上使用pip安装了AWS CLI。安装进行得很顺利。当我运行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()
  File "/usr/local/lib/python3.9/site-packages/awscli/clidriver.py", line 77, in create_clidriver
    load_plugins(session.full_config.get('plugins', {}),
  File "/usr/local/lib/python3.9/site-packages/awscli/plugin.py", line 44, in load_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])
  File "/usr/local/lib/python3.9/site-packages/awscli/handlers.py", line 42, in <module>
    from awscli.customizations.history import register_history_mode
  File "/usr/local/lib/python3.9/site-packages/awscli/customizations/history/__init__.py", line 24, in <module>
    from awscli.customizations.history.db import DatabaseConnection
  File "/usr/local/lib/python3.9/site-packages/awscli/customizations/history/db.py", line 19, in <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

我是否需要安装任何其他模块来修复此错误消息

谢谢

Answer 1

collections.MutableMapping从Python 3.3开始就被弃用，并从Python 3.9开始被正式删除

摘自documentation

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

您可以等待发布与Python 3.9兼容的awscli版本，也可以自己在/usr/local/bin下对aws脚本进行修补（暂时如下所示）：

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