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 .
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/
