| The msvcrt module is part of the standard library on Windows. Your cygwin installation may be incomplete. By the way, why are you importing a private module? _pyio isn't a public API and shouldn't be used. |

| Presumably this issue does prevent us from testing _pyio on Cygwin, which is not ideal. The outside usage of _pyio is definitely not supported, as Christian said, but this may be worth fixing anyway. |

| I am using not using _pyio module directly but I am using cherrypy server which is using this module (more precisely its component cheroot): https://github.com/cherrypy/cheroot/blob/86c6b246ec7cb704c6f96123556db1a083301634/cheroot/makefile.py#L5 Regarding installation of cygwin environment, I can check it in other machine. |

| Could you please file a bug with cherrypy and get it fixed? Cygwin not yet officially supported and stable. Erik is working hard on stable support for 3.7. |

| Right, so you should raise an issue with cherrypy :). You're more likely to get a fix from them quickly, and their usage of _pyio is not correct anyway. Also, note that Cygwin is not (anymore/yet) a fully-supported platform. We're working towards that status, but aren't there yet. |

| This issue seems to duplicate #28459. #28459 has a patch (implement _setmode() by ctypes on _pyio). I'm not sure _setmode() will be used in other places in the future, but the patch just works at the moment. In addition, I have an idea which implements C extension (imitation msvcrt or just cygwin). |

| Indeed, this is a duplicate of #28459. I'll also update the existing patch to a pull request. |
