help

now, wondering if json gem causing problem?

let me know if need of removed information. bug report long removed codes says a lot of information listed here brevity.

per suggestion @maxd, ended having uninstall , reinstall ruby.

here process followed.

  1. i uninstalled ruby command line rvm remove 2.2.1
  2. i reinstall 2.2.1 command line rvm install 2.2.1
  3. then reinstalled rails command line sudo gem install rails
  4. then used bundle install reinstall missing gems
  5. next, used gem install rubygems-update update rubygems 2.0.14 2.1.
  6. then reset gems pristine condition gem pristine --all.
  7. then reason had rerun bundle install because actionmailer 4.2.0 no longer showing being installed, though in list after first bundle install.
  8. finally running rails -v gave me output of rails 4.2.0 instead of error codes.

so, ran rails server , well.
