OSX iTerm2可以将鼠标用于python ncurses,但不能用于C语言中的诅咒

OSX iTerm2可以将鼠标用于python ncurses,但不能用于C语言中的诅咒,python,c,ncurses,Python,C,Ncurses,我正在考虑为一个用C编写的小编辑器提供鼠标支持。该编辑器是围绕ncurses构建的,所以我认为这应该是可能的。我从另一篇文章中获得了这个Python源代码,它运行: import curses from contextlib import contextmanager @contextmanager def open_screen(): scr = curses.initscr() curses.noecho() curses.cbreak() scr.keyp

“这不会运行”没有帮助。确切的问题是什么?代码是否编译?编译过程中是否存在任何错误/警告?如果编译,则运行二进制文件时会发生什么?是否显示任何内容?是否尝试过调试?请发布并尽可能多地添加有关此问题的信息。提供的信息远远不够d、 非常感谢,我在第一步混合了太多东西:-)
