Fle*_*seo 5 ruby windows ncurses
我正在尝试在 Windows 上为 ruby 安装 ncurses。我之前没有在我的机器上安装 ncurses。我认为拥有它所要求的“ruby devkit”就足够了,但现在我被要求指定选项......我不知道选择哪些选项,或者我是否需要做/安装其他东西要安装 gem:
C:\Ruby193\Devkit>gem install ncurses -- --ruby=C:/Ruby193/bin/ruby --without-make-prog --without-opt-dir
Temporarily enhancing PATH to include DevKit...

多么痛苦,我只想安装这个 gem,这样我就可以运行这个:
require 'curses'
cols = Curses.stdscr.maxx
msg = "random_string"
str = msg.center(msg.length + cols - msg.length - 5 - 3)
puts "<!-- #{str}-->"

ruby ncurses gem 要求在计算机上安装 ncurses。据我所知ncurses还没有移植到windows上。所以我认为你不会让它发挥作用。
可能还有其他方法可以找出窗口上的屏幕宽度,但我无法帮助您。
