问题:无法在 Ubuntu 14.04 上安装 kgio 2.8.1

注意: 我运行的是 Ubuntu,而不是 Windows。

这是尝试安装 kgio 时发生的情况。我是否缺少依赖项,我要安装什么?

gilani@debris$ gem install kgio -v '2.8.1' 
Building native extensions.  This could take a while...
ERROR:  Error installing kgio:

解答

正如@bjhaid 在评论中回答的那样,并没有跟进。我会自己在这里发布以关闭问题:

您正在尝试针对比针对其编写的版本更新的 ruby 版本编译 gem,kgio 2.8.1 于 2013 年发布(bogomips.org/kgio.git/tag/?hu003dv2.8.1),ruby 2.2 .1 于 2015 年 3 月发布 (ruby-lang.org/en/news/2015/03/03/ruby-2-2-1-released)
