Ansible ec2.py 动态清单错误：ImportError: cannot import name 'ec2'

Question

My current machine crashed and I have to setup ansible again on the new one using the same methodologies but It seems I am missing somethings. I need to use version 2.X for consistency reasons as we have not upgraded yet.

I heavily used ec2.py and ec2.ini so when I run

~ python /Users/joseph/infrastructure_as_code/ansible_projects/inventory/ec2.py
Traceback (most recent call last):
File  "/Users/joseph/infrastructure_as_code/ansible_projects/inventory/ec2.py", line 172, in <module>
from ansible.module_utils import ec2 as ec2_utils
ImportError: cannot import name 'ec2' from 'ansible.module_utils'  (/Users/joseph/.pyenv/versions/pypy3.8-7.3.7/lib/pypy3.8/site-  packages/ansible/module_utils/__init__.py)

Here is my setup.Fresh MacBook Pro M1.

#Mac, no prior ansible installation either brew or pip

## Content of ~/.ansible.cfg
[defaults]

   3.10.2
   3.8.12
   ansible-2x
   * pypy3.8-7.3.7 (set by /Users/joseph/.pyenv/version)
   pypy3.8-7.3.7/envs/ansible-2x

I have read couple of solution around about the PATH and had high hopes about the interpreter_python setting in the config file but none of that worked. So I am not sure what is wrong were, I have also switched to different version of python but it did nothing. Not sure what's missing, I would appreciate some hand in fixing this. Thanks in advance

Answer 1

It's because you have ansible v2.10.17 whereas that file only exists in the v2.9 series: https://github.com/ansible/ansible/blob/v2.9.27/lib/ansible/module_utils/ec2.py

• 404: https://github.com/ansible/ansible/blob/v2.12.2/lib/ansible/module_utils/ec2.py
• 404: https://github.com/ansible/ansible/blob/v2.11.8/lib/ansible/module_utils/ec2.py
• 404: https://github.com/ansible/ansible/blob/v2.10.17/lib/ansible/module_utils/ec2.py

In the future, pip freeze will emit a requirements.txt file with the versions pinned to the current ones in use, which can help this kind of drift
