ruby app is giving problems with incompatible libraries - ruby-on-rails

Question

while generating controllers, I am getting this error message:

Nothing I have tried makes it stop. I have reinstalled every gem it complains about, but the changes do not persist. I've followed every fix I can find/understand but I am chasing my tail on this one.

Your rails is not linked with the right ruby version. Use the following code:
rvm use ruby-<version number> like: (rvm use ruby-2.1.4)
then reinstall the bundler:
gem uninstall bundler
gem install bundler
bundle install once again with the new version.
bundle install
Then proceed with your rails g command.
