Fedora 24 - ошибка установки Ruby on Rails

Question

Я попытался установить рельсы на моем новом устройстве Fedora 24. Я следовал этому руководству https://developer.fedoraproject.org/tech/languages/ruby/ror-installation.html.

Но я получил эту ошибку:

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

current directory: /usr/local/share/gems/gems/nio4r-1.2.1/ext/nio4r 
/usr/bin/ruby -r ./siteconf20160918-22847-14vriyi.rb extconf.rb

Could not create Makefile due to some reason, probably lack of necessary 
libraries and/or headers. Check the mkmf.log file for more details. You may 
need configuration options. 

Provided configuration options:

--without-opt-dir

--without-opt-include=${opt-dir}/include

from /usr/share/ruby/mkmf.rb:1090:in `have_header' 
from extconf.rb:3:in `<main>' 

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

/usr/local/lib64/gems/ruby/nio4r-1.2.1/mkmf.log 

extconf failed, exit code 1 

Gem files will remain installed in /usr/local/share/gems/gems/nio4r-1.2.1 for inspection. 
Results logged to /usr/local/lib64/gems/ruby/nio4r-1.2.1/gem_make.out 

Я гугле решение, но я не был успешным. Не могли бы вы дать мне совет? Спасибо

Answer 1

Установили ли вы «средства разработки» на сообщение об ошибке в ваших журналах?

The compiler failed to generate an executable file. (RuntimeError)

You have to install development tools first.

От the linked Fedora ROR installation guide:

sudo dnf group install "C Development Tools and Libraries"
