Now I'm using the Rubymine instead of pry-debugger as my primary Rails environment, Rubymine has much great debug facility and what's more, I spend $17 when the JetBrains offer 75% off at the Mayan Doomsday.

But I found a problem that rubymine always refuse to enter the debug mode when I using my pl-form project in below warning:

debugger-1.2.3/lib/ruby_debug.so: warning: already initialized constant VERSION

finally I found prject Gemfile need a little review:

group :development do
  gem 'quiet_assets'
  # Disable below two line if you using rubymine
  #gem 'pry-rails'
  #gem 'pry-debugger'
end
