Woooww it's work, @alaouy Thanks.

Thanks @alaouy your comment definitely got me on the right track.

If bundle install will not work for you because you recently updated to El Capitan 10.10
Your error message will look like this:

ERROR: "bundle install" was called with arguments ["json-1.8.3"] or this:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension

To get around this issue try:

$xcode-select --install
$sudo chown -R (whoami):admin /usr/local
$sudo xcode-select --reset
$softwareupdate --install
$sudo xcodebuild -license

Then agree or disagree with Apples license.

Thanks @alaouy

Thanks @kevindelord ! worked great on macOS 10.12.4 - Ruby 2.4.1

I'm on OSX Sierra

bundle update json from @kevindelord. This worked for me.

thanks @Juice007. most helpful. worked on Mac OS X El Capitan 10.11.6 with Ruby 2.4.0

bundle update json fixed the issue

I am a noob in ruby and I saw @Juice007 's method helps a lot of people then I really want to give a try. But really not sure how to add a line in my gemfile. Do I need to run something in terminal to open and edit the file? or follow the direction locally and edit in a file whose name is "Gemfile". If it's the second one, I found not only one file whose name is "Gemfile", then which one should I choose?

@zhaoye159 open the Gemfile in your project root and add the line to it using your editor of choice. You will then need to run bundle install on the command line.

Running on OSX Sierra, this error "Failed to build gem native extension" for json (1.8.3) was not fixable with xcode-select in my case

but downgrading my ruby version from 2.4.1 to 2.3.4 fixed it, as Juice007 pointed out above.

@alaouy, thanks)

Thanks @alaouy :D

Thanks @kevindelord I have finally solved the problem.
brew install coreutils doesn't work on my macOS and I don't know why.
but, after bundle update json and bundle install , it worked and there is no error like the following any more.

An error occurred while installing json (1.8.3), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

Does anyone knows solution for archlinux? What package I have to install instead of sudo apt-get install libgmp3-dev?

P.S. tried yaourt lib32-gmp4 - no luck

thanks for help! @vhosakot

In case of my mac, i can't run: sudo apt-get or yum.
So i tried brew install coreutils but it also didn't work for me.
Including gem uninstall json with reinstall json -v '1.8.3', any method didn't work for me.

Following @Juice007, in MacOS Sierra,
the ruby version 2.4.0 is not compatible with json 1.8.3.

Add this line at before your crash:
gem 'json', github: 'flori/json', branch: 'v1.8'
then bundle install

Finally, it works for me very well.
thanks @Juice007 very much.

For Arch Linux users (cc @BjornMelgaard):

sudo pacman -S mpfr

should do the trick.

Thanks @alaouy

brew install coreutils didn't do the trick and gem uninstall json won't do either because it's a default gem. try bundle update json and then run bundle install, that could work.

@danielhaim1 It works.Thanks :)

Either Ruby or gem is new to me.
On Macos,I use brew to install ruby and gem,but by default brew cannot replace the ruby bin file which system already has;And brew link ruby --force said you should do:
export PATH="/usr/local/opt/ruby/bin:$PATH"; export LDFLAGS="-L/usr/local/opt/ruby/lib"; export CPPFLAGS="-I/usr/local/opt/ruby/include";
This finally works on my Mac,whish this could help for newbies.

You should upgrade json-1.8.5+ or the stable versions of Ruby like 2.5 or 2.6.

Thanks @alaouy your comment definitely got me on the right track.
