Ruby on rails 如何修复在Fedora上安装Rails时出现的错误

我是Fedora和Rails的新手，不知道如何解决这个问题。以下是错误消息：

Building native extensions.  This could take a while...
ERROR:  Error installing rails:
ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /usr/local/lib64/gems/ruby/nokogiri-1.6.7.2/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /usr/local/share/gems/gems/nokogiri-1.6.7.2 for inspection.

要了解此扩展未能编译的原因，请检查mkmf.log，该日志可在此处找到：
/usr/local/lib64/gems/ruby/nokogiri-1.6.7.2/mkmf.log
extconf失败，退出代码1
Gem文件将继续安装在/usr/local/share/gems/gems/nokogiri-1.6.7.2中以供检查。
结果记录到/usr/local/lib64/gems/ruby/nokogiri-1.6.7.2/gem_make.out

这里的关键信息是

您必须首先安装开发工具

它应该安装在

dnf install @development-tools
