python - 运行 flake8 给出 - AttributeError : 'OptionManager' object has no attribute 'config_options'

Question

我使用以下命令安装了 flake8。

pip3 install flake8

从终端执行 flake8 会出现以下错误。

Traceback (most recent call last):
  File "/home/bilesh/.local/bin/flake8", line 11, in <module>
    sys.exit(main())

从 2016 年开始发现以下错误，但似乎已修复。

不确定我在这里做错了什么。任何帮助将不胜感激。

$ pip3 freeze | grep flake8
flake8==3.7.7
flake8-docstrings==1.3.0
flake8-polyfill==1.0.2

因此，根据 phd 发表的评论在这个问题上，我做了以下事情。

1. 卸载flake8:pip3卸载flake8
2. 清理目录:sudo rm -R/path/to/directory/flake8
3. 重新安装 flake8:pip3 install flake8

它成功了:)
