今天用vscode编辑python代码，vscode提醒安装pylint。所以我安装了python externsion，同时我在终端安装了oylint use cmd python -m pip install -U pylint --user。但是终端上报的信息是

    Traceback (most recent call last):
  File "C:\Users\DELL\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 183, in _run_module_as_main

目前我找不到解决问题的有效措施，所以在这里寻求帮助，谢谢！

【问题讨论】：

你的当前工作目录中是否有名为copy.py的文件？

标签： python visual-studio-code attributeerror pylint

【解决方案1】：

您的工作区中可能有一个名为copy 的模块。重命名它，这样它就不会影响 Python 的 stdlib 中的内置 copy 模块，并且应该让 pip 正常运行。
