pyreadline not compatible with Python 3.10 REPL on Windows

[emcf]

I am using python 3.10.8, and my LaTeX-OCR suddenly broke overnight, giving the following error:

Traceback (most recent call last):

AttributeError: module 'collections' has no attribute 'Callable'

Another issues thread (hylang/hy#2114) suggests this has to do with pyreadline not being compatible with the windows python 3.10. liyiliuxingyu says the following, which fixed this for me:

Please change the code in line 8 of "c:\python\lib\site-packages\pyreadline\py3k_compat.py" to return isinstance(x, collections.abc.Callable), so that it can run successfully.

Hope this helps.

Thanks for the report!
I don't like to edit packages in the site-packages directory.
I found out that pyreadline3 is a maintained fork of the original package and it supports py3.10+.
I've added it as a dependency for windows only.
