ImportError: cannot import name 'Iterable' from 'collections'

[LingkKang]

I am going through the coala tutorial, and run into a problem.

I cloned the coala-tutorial repo to my machine, and when I run command coala --files=src/\*.c --bears=SpaceConsistencyBear --save in the coala-tutorial directory, I got this error message:

[ERROR][21:11:49] An unknown error occurred. This is a bug. We are sorry for the inconvenience. Please contact the developers for assistance. During execution of coala an exception was raised. This should never happen. When asked for, the following information may help investigating:

And similarly, when I run coala --files=src/\*.py --bears=PEP8Bear --save, I got:

[ERROR][21:14:05] An unknown error occurred. This is a bug. We are sorry for the inconvenience. Please contact the developers for assistance. During execution of coala an exception was raised. This should never happen. When asked for, the following information may help investigating:

I'm not sure what's wrong with it. Did I ignore something important?

For your information, I installed coala with command pip install coala-bears, and other thing are as followed:

• OS: Windows 10 Pro 21H2
• Python: 3.10.2
• pip: 21.2.4
• coala: 0.11.0
• coala-bears: 0.11.1
• coala-utils: 0.6.7

As you may see, I didn't install python in default location, but I don't think this could be the reason.

Many thanks in advance.

UPDATE

I found this blog and it said collections.Callable was moved into collections.abc.Callable since python 3.10 and above.

And I found there is a new maintained version of pyreadline, named as pyreadline3.

So I ran command pip install --upgrade pyreadline3, and ran coala --files=src/\*.c --bears=SpaceConsistencyBear --save again, surprisingly, error message reads like:

[ERROR][23:25:21] An unknown error occurred. This is a bug. We are sorry for the inconvenience. Please contact the developers for assistance. During execution of coala an exception was raised. This should never happen. When asked for, the following information may help investigating:

ImportError: cannot import name 'Iterable' from 'collections' (D:\Python3.10\lib\collections\__init__.py)

At least it got shorter. 🤷‍♂️

[LingkKang]

From the python docs, collections.Iterable was moved to collections.abc.Iterable.

So maybe this is the reason why there is an ImportError.

coala/coalib/misc/DictUtilities.py

Line 1 in 734b857

from collections import defaultdict, Iterable, OrderedDict
