ruby-on-rails - Gem::Ext::BuildError: 错误:无法为 rails 版本 4.2.6 构建 gem native 扩展

Question

我创建了新的 Rails 应用程序并尝试运行 bundle install 它显示了这个错误，

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
current directory: /var/lib/gems/2.3.0/gems/json-1.8.6/ext/json/ext/generator/usr/bin/ruby2.3 -r ./siteconf20170704-11395-12tpg5u.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h
extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.3.0/gems/json-1.8.6 for inspection.
Results logged to /var/lib/gems/2.3.0/extensions/x86_64-linux/2.3.0/json-1.8.6/gem_make.out

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

请给我一些建议，在此先感谢。

Answer 1

如果您有 Mac 或 Linux 机器，请尝试以下命令:

sudo apt-get install ruby-dev

如果失败了，你的输出是什么:

gem install json -v '1.8.6'

(请复制并粘贴所有输出)。

我不确定如何为 Mac 修复它，但人们对 brew install ruby​​ 有积极的体验。
