ImportError: No module named '_curses' when trying to import blessings
Meanwhile - Python 2.7.15 on Windows 10 - curses support can be added by:
pip install windows-curses
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.
