AttributeError: module ‘flake8.options.config‘ has no attribute ‘ConfigFileFinder‘

升级flake8后，执行pflake8时报错了：

Traceback (most recent call last):
  File "/Users/lian/Library/Caches/pypoetry/virtualenvs/huiyuan-Ur7Wlhj0-py3.10/bin/pflake8", line 5, in <module>
    from pflake8.__main__ import main
  File "/Users/lian/.local/pipx/venvs/poetry/lib/python3.10/site-packages/pflake8/__init__.py", line 54, in <module>
    class ModifiedConfigFileFinder(flake8.options.config.ConfigFileFinder):
AttributeError: module 'flake8.options.config' has no attribute 'ConfigFileFinder'

安装的包版本如下：

% pip list|grep flake8                                                       :( 1 22-08-25 - 23:09:32
flake8             5.0.4
pyproject-flake8   0.0.1a5

原因是flake8最新版的5.0+与旧版不兼容，导致pflake8的补丁失效了

解决方法一：

用回4.0版本的flake8

pip install -U pyproject-flake8  # 会自动卸载掉最新版的flake8并安装匹配的版本

解决方法二：

使用开发版的pflake8

git clone https://github.com/csachs/pyproject-flake8.git -b patch-via-ast
pip install -e ./pyproject-flake8
