gem install json issue with Mac OS X 10.11

I'm trying to install Ruby/JSON on Mac OS X 10.11. However, the gem install command gives the error message:

smcho@macho ruby-rails-sample> gem install json
Building native extensions.  This could take a while...
ERROR:  Error installing json:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/smcho/.rvm/gems/ruby-2.2.1/gems/json-1.8.3 for inspection.
Results logged to /Users/smcho/.rvm/gems/ruby-2.2.1/extensions/x86_64-darwin-14/2.2.0-static/json-1.8.3/gem_make.out

The message says make: ./install: No such file or directory, but I'm not sure how to fix this issue.

Is this a known issue, or is there a way to bypass this one?

This is my system version. I executed gem update --system to get the latest version.

Solution

  • I should have used the latest ruby (2.2.3) not the old one (2.2.1)

    ruby-rails-sample> rvm --default use 2.2.3
