尝试从本地机器配置 githubpage 时发生以下错误：
显示错误：
An error occurred while installing ffi
(1.9.14), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.9.14'`
succeeds before bundling.
运行命令 gem install ffi -v '1..9.14' 出现以下错误。
sudo gem install ffi -v '1.9.14'
Building native extensions. This could take a while...
ERROR: Error installing ffi:

Gem files will remain installed in /var/lib/gems/2.3.0/gems/ffi-1.9.14 for inspection.

然后我查看了日志文件：gem_make.out，其中显示以下错误
sudo cat /var/lib/gems/2.3.0/extensions/x86-linux/2.3.0/ffi- 1.9.14/gem_make.out

请建议我下载 ruby.h 并将其添加到特定位置的方法，或者帮助我以正确的方式安装 gem。

我也遇到过类似的问题。
安装 ffi（1.9.14）时发生错误，Bundler 无法继续。
gem install ffi -v '1.9.14'捆绑之前请确保成功。
我修复了它sudo apt-get install ruby-dev.我找到了答案这里
