step7:

App is not available in web.

show below info :

You have already activated rake 0.9.6, but your Gemfile requires rake 10.3.2. Using bundle exec may solve this. (Gem::LoadError)

  /opt/rh/ruby200/root/usr/share/gems/gems/passenger-4.0.18/helper-scripts/rack-loader.rb:3:in `<main>'


Expected results:
should not get the error in step7, since the rake 10.3.2 already installed during git push.
