当我尝试运行pip命令时出现“错误的文件描述符”错误

Question

当我尝试运行任何pip或anaconda命令时，出现此错误。我已经尝试过重新安装python。

我正在使用python 3.8.5

    from .compat import is_py2, builtin_str, str
  File "C:\ProgramData\Anaconda3\lib\site-packages\pip\_vendor\requests\compat.py", line 64, in <module>
    from http.cookies import Morsel
  File "<frozen importlib._bootstrap>", line 983, in _find_and_load
  File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 677, in _load_unlocked
  File "<frozen importlib._bootstrap_external>", line 724, in exec_module
  File "<frozen importlib._bootstrap_external>", line 859, in get_code
  File "<frozen importlib._bootstrap_external>", line 917, in get_data
OSError: [Errno 9] Bad file descriptor

在这里我尝试使用pip安装pygame
