Question

安装json（1.8.6）时发生错误，Bundler无法继续。在捆绑之前确保gem install json -v '1.8.6'成功。

在Gemfile中：

rails被解析为4.2.6，这取决于

actionmailer was resolved to 4.2.6, which depends on
  actionpack was resolved to 4.2.6, which depends on
    actionview was resolved to 4.2.6, which depends on
      rails-dom-testing was resolved to 1.0.9, which depends on
        rails-deprecated_sanitizer was resolved to 1.0.3, which depends on
          activesupport was resolved to 4.2.6, which depends on
            json

Gem :: Ext :: BuildError：错误：无法构建gem原生扩展。

current directory: /tmp/bundler20180201-46774-s2jlm4json-1.8.6/gems/json-1.8.6/ext/json/ext/generator
/usr/bin/ruby2.3 -r ./siteconf20180201-46774-16pojxx.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

这是什么意思以及如何纠正它。我已经尝试过更新和升级方法是否有其他方法可以删除某些依赖项。

Answer 1

如有必要，请尝试更新源列表，否则删除最近安装的大多数文件，然后从头开始重新安装。如果需要，另外安装每个包装的包装

sudo apt-get uprade

也可以。

Answer 2

尝试一下：

bundle update

如果发生捆包错误

gem install bundler  #After that run below command too.

bundle install

在rails bundle install上给出错误
