cygwin python安装：“致命的python错误：init_fs_编码：无法获取文件系统编码的python编解码器”

Question

我正在尝试安装一个新的cygwin，并通过cygwin安装python。我已经这样做了，安装也完成了，但是当我尝试运行python3.8时，我得到了一个致命的python错误：

$ python3.8
Python path configuration:
  PYTHONHOME = 'C:\Users\cmhac\AppData\Local\Programs\Python\Python38'
  PYTHONPATH = 'C:\Users\cmhac\AppData\Local\Programs\Python\Python38'
  program name = 'python3.8'
  isolated = 0
  environment = 1
  user site = 1
  import site = 1
  sys._base_executable = '/usr/bin/python3.8.exe'
  sys.base_prefix = 'C'
  sys.base_exec_prefix = '\\Users\\cmhac\\AppData\\Local\\Programs\\Python\\Python38'
  sys.executable = '/usr/bin/python3.8.exe'
  sys.prefix = 'C'
  sys.exec_prefix = '\\Users\\cmhac\\AppData\\Local\\Programs\\Python\\Python38'
  sys.path = [
    'C',
    '\\Users\\cmhac\\AppData\\Local\\Programs\\Python\\Python38',
    'C/lib/python38.zip',
    'C/lib/python3.8',
    '\\Users\\cmhac\\AppData\\Local\\Programs\\Python\\Python38/lib/python3.8/lib-dynload',
  ]
Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'

Current thread 0x0000000800000010 (most recent call first):
<no Python frame>

我怎么开始修复这个？python38.exe文件就在那里，看起来一切正常。在任何其他python安装中都没有此错误

我看到了这个错误： 致命的Python错误：init_fs_encoding:无法获取文件系统编码的Python编解码器 Python运行时状态：核心已初始化 ModuleNotFoundError:没有名为“encodings”的模块

如果将这两个环境变量设置为nil，则问题应消失： 设置Python窝= 设置PYTHONPATH=
