最近我在VSCode中运行pylint时遇到了下面的错误信息。 当我在命令行中使用“pylint <file/to/python/file>”运行pylint时，一切都正常。 直到几周前，它一直运行得很好。系统没有明显的变化。

VSCode版本：1.87.2 Python版本：3.12.0和3.9.5 操作系统：Windows 10

任何建议都非常感谢，谢谢

  • 我查看了pylint的GitHub仓库和StackOverflow，没找到相关的问题
  • 重新安装pylint扩展也没有帮助
  • 删除VSCode工作区也没有效果

解决方案

用户设置的json文件里有这么一个设置：
"pylint.path": ["--max-line-length=120"]
这个设置引起了问题，因为它改变了pylint的路径。

在日志中也能看到这个问题：
2024-03-19 17:52:59.413 [info] --max-line-length=120 --version。
正常情况下应该是这样的：
2024-03-20 23:11:02.400 [info] c:\Program Files\Python312\python.exe -m pylint --version。

如果其他人也需要分析类似的问题，我的处理方法是：

  • 重新安装了pylint扩展 -> 没有效果
  • 删除了C:\Users\test_user\AppData\Roaming\Python\Python312，因为里面几乎是空的（在另一台电脑上没有这个文件夹） -> 没有效果
  • 用系统安装程序重新安装了VSCode，而不是用户安装程序 -> 没有效果
  • 检查了我的用户settings.json文件中与pylint相关的设置（在最初的日志中可以看到）
    • "pylint.args": ["--max-line-length=120"] -> 删除了 -> 没有效果
    • "pylint.path": ["--max-line-length=120"] -> 删除了 -> 找到了根本原因
