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

Answer 1

❯ vim +16 /home/g/.local/lib/python3.10/site-packages/frozendict/__init__.py

并以这种方式修改第 16 行：

- class frozendict(collections.Mapping):
+ class frozendict(collections.abc.Mapping):

像新的一样:)

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