i'm working on project using:

i tried run bundle install keep getting following error:

gem::ext::builderror: error: failed build gem native extension. 

and, following:

an error occurred while installing nio4r (1.0.0), , bundler cannot continue. make sure `gem install nio4r -v '1.0.0'` succeeds before bundling. 

when try running gem install nio4r -v '1.0.0':

if working on mac osx above version 10.11.x, following approach worked me:

gem install nio4r -v '1.1.0' -- with-cflags="-std=c99"
