无法在 Ubuntu 14.04 上安装 kgio 2.8.1
Can't install kgio 2.8.1 on Ubuntu 14.04
注：我是运行Ubuntu，不是Windows。
这是在尝试安装 kgio 时发生的情况。我是否缺少依赖项，我应该安装什么？
gilani@debris$ gem install kgio -v '2.8.1'

正如@bjhaid 在评论中回答的那样，并没有跟进。我会 post 自己在这里关闭问题：
you are trying to compile the gem against a version of ruby newer than
what it was written against, kgio 2.8.1 was released in
2013(bogomips.org/kgio.git/tag/?h=v2.8.1), ruby 2.2.1 was released
March 2015 (ruby-lang.org/en/news/2015/03/03/ruby-2-2-1-released)
这些组合在 Ubuntu 16.04 上帮助了我：
apt-get install ruby-kgio
bundle update kgio
发现如果你的 rvm 没有加载，你可能会收到同样的错误。
验证是否加载了 rvm try:
rvm use 2.x.x
如果您收到以下警告：
You need to change your terminal emulator preferences to allow login
shell. Sometimes it is required to use /bin/bash --login as the
command. Please visit https://rvm.io/integration/gnome-terminal/ for
an example.
这可能也是你的情况:-)
/bin/bash --login
rvm use 2.x.x
在敲了大约一个小时后为我解决了+为什么会发生这种情况
