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

wpull 2.0.3 works fine under Python 3.6 and breaks under 3.7 for unrelated reasons.
Python 2 is deader than dead, and wpull hasn't supported it since 2014.

The crash you reported is real though. Python moved the ABCs to collections.abc back in Python 3.3, and the aliases in collections were removed in 3.10.

I think wpull supports python 3.5 max.

[allanlaal]

did not work with 3.5 nor 2.7

What do you mean by "did not work"? You have to install the dependencies again if you're changing python versions.

On 3.6 I get:
