python - Visual Studio Code 安装 python 扩展 pylint 失败

问题描述

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python -m pip install -U pylint --user在终端安装了oylint use cmd。但终端上报的信息

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

    cpy = copy.copy( self )
AttributeError: module 'copy' has no attribute 'copy'

目前我找不到解决问题的有效措施，所以我在这里寻求帮助，谢谢！

解决方案

您的工作区中可能有一个名为copy. 重命名它，这样它就不会从 Python 的 stdlib 中隐藏内置copy模块，并且应该让 pip 正常运行。
