Windows：Python 3.7 中遇到 ImportError: No module named '_curses'
最简单的解决方案：
pip install windows-curses
问题原因：
Windows 平台没有安装curses。因为Python认为该功能主要在Unix上使用。
The curses module is not supported on Windows machines. From the module documentation:
While curses is most widely used in the Unix environment, versions are available for DOS, OS/2, and possibly other systems as well. This extension module is designed to match the API of ncurses, an open-source curses library hosted on Linux and the BSD variants of Unix.
Install the unofficial windows binary for curses from here and try again.
