无法安装 json gem 1.8.6 - 无法在 Ubuntu 上构建 gem 本机扩展

Can't install json gem 1.8.6 - failed to build gem native extension on Ubuntu

Ubuntu 16.04 上的 Bundler 在尝试安装 JSON 时出现以下错误。

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing json (1.8.6), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.6'` succeeds before bundling.

看起来 gem 扩展因为缺少头文件而无法编译。我能做什么?

好像有similar problem on RedHat 7.

如果是 Ubuntu,解决方案似乎是安装 ruby-dev 包。

sudo apt-get install ruby-dev
