I cannot express my abject frustration at times with the Ruby ecosystem in general and bundler in particular. When you hit this bug:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension. current directory: /usr/local/rvm/gems/ruby-2.3.1/gems/json-1.8.1/ext/json/ext/generator /usr/local/rvm/rubies/ruby-2.3.1/bin/ruby -r ./siteconf20161011-22175-140avvd.rb extconf.rb creating Makefile current directory: /usr/local/rvm/gems/ruby-2.3.1/gems/json-1.8.1/ext/json/ext/generator make "DESTDIR=" clean current directory: /usr/local/rvm/gems/ruby-2.3.1/gems/json-1.8.1/ext/json/ext/generator make "DESTDIR=" compiling generator.c In file included from generator.c:1:0: ../fbuffer/fbuffer.h: In function ‘fbuffer_to_s’: ../fbuffer/fbuffer.h:175:47: error: macro "rb_str_new" requires 2 arguments, but only 1 given VALUE result = rb_str_new(FBUFFER_PAIR(fb)); ^ ../fbuffer/fbuffer.h:175:20: warning: initialization makes integer from pointer without a cast [enabled by default] VALUE result = rb_str_new(FBUFFER_PAIR(fb)); ^ make: *** [generator.o] Error 1 make failed, exit code 2 Gem files will remain installed in /usr/local/rvm/gems/ruby-2.3.1/gems/json-1.8.1 for inspection.

Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
I've hit this error, I suspect, a few hundred times and I always forget the solution. And I'm not the only one. Dv and I hit this together today and we shot about 20 minutes today to need this:
gem install json -v1.8.3
Thank you Stack Overflow for this answer. Even if it was buried so deep in the thread that I almost missed it.
