Ruby on rails – 捆绑安装期间出错
我一直在谷歌上面搜索这个错误，但我无法解决这个错误：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. /usr/bin/ruby2.1 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 /home/dyego/.bundler/tmp/9200/gems/sqlite3-1.3.9 for inspection.

mkmf.rb在/usr/lib/ruby/include/ruby.h找不到ruby的头文件
我得到了一些类似的问题： 安装json gem时错误’mkmf.rb无法找到ruby的头文件’
但我已经安装了ruby-dev：
sudo apt-get install ruby-dev Reading package lists... Done Building dependency tree Reading state information... Done ruby-dev is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 72 not upgraded.
我真的很难解决这个问题（即使它看起来很简单）。
尝试为您的Ruby版本2.1安装ruby-dev库
$ sudo apt-get install ruby2.1-dev
在尝试为SASS开发安装指南针时，在fedora上有类似的错误
gem install compass
失败了
构建原生扩展。 这可能需要一段时间…错误：安装罗盘时出错：错误：无法构建gem原生扩展。
/ usr / bin / ruby extconf.rb mkmf.rb在/usr/share/include/ruby.h找不到ruby的头文件
跑吧
yum -y install gcc ruby-devel rubygems
然后能够成功再次运行安装。
