Cannot install Rails

Hello

Upon starting a new RoR project, I chose to use RVM-ruby-2.2.3 (already installed to my machine)

However, if I chose to install the newest version of Rails (RubyMine's new project dialog proposes 4.2.4) the installation process fails with the following:



Following gems were not installed:
rails (4.2.4):  Error installing rails:

Thanks in advance
