extconf failed, exit code 1

when installing bundle it returns(starts at line 117 in the logs ):

Installing nio4r 1.2.1 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

So the bundle can't be installed. It returns at the end :

An error occurred while installing nio4r (1.2.1), and Bundler cannot continue.
Make sure that `gem install nio4r -v '1.2.1'` succeeds before bundling.

Note :I have tried the solutions in other questions, but it is still the same. If it is possible to install "nio4r" manually please tell me how .

This may be related: GCC compilation error when installing Nokogiri

I found a error. i had a 2 gcc versions installed on my system and I just run brew unlink gcc and that solved the problem.

This was my case too. brew unlink gcc worked

If you use Windows and installed ruby with RubyInstaller with version more or equal to 2.4, than you should not install DevKit from RubyInstaller website and only use 'msys64' which is installed after Ruby with RubyInstaller (make sure you type number 3 to install both msys and mingw). Delete devkit directory and its path from PATH environment variable, so when rubygems will try to install nio4r and call C compilers, it will call msys ones. Read here https://rubyinstaller.org/2017/05/25/rubyinstaller-2.4.1-1-released.html for more info about MSYS2 and DevKit in RubyInstaller

Had this same issue on Ubuntu 16.04. What I did to fix this :

Remove Gemfile.lock : sudo rm Gemfile.lock Installed Ruby-Dev:

sudo apt-add-repository ppa:brightbox/ruby-ng sudo apt-get update sudo apt-get install ruby2.4-dev

and the important step : REBOOT!

I had a similar problem and running this command solved my issue.

bundle config build.nio4r --with-cflags="-std=c99"

Now you can successfully run bundle install afterwards.

My son fixed this problem for me. The problem was that I installed first, Ruby and then the Rails installer. So I had to uninstall Ruby and reinstall with the Rails installer only.

I came across this problem as i was setting up rails too. (looking for an alternative to php).

I realized that i had installed x86 ruby with x64 Devkit, so i first downloaded x64 ruby which i installed and uninstalled the x86 version. I made sure my path variables were well set.
Then i installed devkit using the instructions on this page http://rubyonwindowsguides.github.io/book/ch02-04.html
Finally i installed rails and it worked fine without the errors this time

Hope this helps

I am facing the same issue while I was trying to upgrade my Rails to V5.0.0, I follow this instruction and it works perfectly. Read the section "Install the Ruby DevKit" here >> http://jekyll-windows.juthilo.com/1-ruby-and-devkit/
