Visual Studio Code安裝python擴展pylint失敗

Question

今天，我使用vscode編輯器python代碼，該vscode提醒安裝pylint。 所以我安裝python externsion，同時安裝oylint，請在終端中使用cmd python -m pip install -U pylint --user 。 但是終端報告了

    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)
  File "C:\Users\DELL\AppData\Local\Programs\Python\Python36\lib\runpy.py", line 142, in _get_module_details

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

目前我找不到解決該問題的有效措施，所以在這里我尋求幫助，謝謝！

您的工作區中可能有一個名為copy的模塊。 重命名該名稱，這樣它就不會掩蓋Python stdlib中的內置copy模塊，並且應該可以讓pip正常運行。
