Ruby on rails Can'；t在Ubuntu 14.04上安装kgio2.8.1

注意：我运行的是Ubuntu，不是Windows

这就是尝试安装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' 
Building native extensions.  This could take a while...
ERROR:  Error installing kgio:

正如@bjhaid在评论中回答的那样，他没有跟进。我会亲自在这里发布，以关闭questoin：

您正试图根据比以前更新的ruby版本编译gem 它所针对的是，kgio 2.8.1于年发布 2013年（bogomips.org/kgio.git/tag/？h=v2.8.1），ruby 2.2.1发布 2015年3月（ruby-lang.org/en/news/2015/03/03/ruby-2-2-1-released）

---

这些因素的结合在Ubuntu 16.04上帮助了我：

apt get install ruby kgio

---

捆绑包更新kgio

发现，如果未加载rvm，则可能会收到相同的错误。 要验证rvm是否已加载，请尝试：

rvm use 2.x.x

如果您收到以下警告：

您需要更改终端仿真器首选项以允许登录 壳有时需要使用

/bin/bash--login

作为 指挥部。请访问 举个例子

这可能也是您的情况：-）

在头部撞击大约一个小时后为我解决了+为什么会发生这种情况？

Does/home/gilani/.rvm/gems/ruby-2.2.1/extensions/x86_64-linux/2.2.0/kgio-2.8.1/gem_-make.out“还告诉你什么吗？”theTinMan根本没有，它包含上面的错误文本，除了最后两条语句，当然，你正试图根据一个比它所用版本更新的ruby版本编译gem，kgio 2.8.1于2013年发布（），ruby 2.2.1于2015年3月发布（）@bjhaid修复了它！谢谢你能把它贴出来作为答案吗？我会把它标记为已回答：）在过去的一个小时里，我一直在努力让我的旧rails项目与ruby

2.3.1

一起工作。无论如何，谢谢。不幸的是，这对我没有帮助。

/bin/bash --login
rvm use 2.x.x
