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.

try using gem 'json', github: 'flori/json', branch: 'v1.8'

@alepore
It works. Thanks!
But! Used 1.8.5
Can you publish last version of gem '1.8' - to '1.8.5' ?

[alepore]

@Sega100500 also, are you aware that the json gem is already included in ruby 1.9.3+?
Try removing the whole dependency, if possible

[Sega100500]

@alepore
Where dependency?! In Ruby on Rails?!!

@alepore

try using gem 'json', github: 'flori/json', branch: 'v1.8'

It possible for few projects... But I have too many projects on RoR 3.2.xx and 4.2.xx
Edit each Gemfile - it not resolve a problem

@alepore
gem 1.8.3 has an error. In use with Ruby 2.4.0
Please FIX IT.
Or... 1.8.5 must be edge for gem 'json' -v 1.8
