Beginners Rails - error in Helloworld

I am trying Ruby on Rails for the first time and following the page at

I think I have done kind of ok with the installation and got to the
"Welcome aboard" page. But the Say "Hello", Rails part is not working.
Getting ExecJS::ProgramError in Welcome#index.

I probably have missed something in the installation process.

Attaching error screens and the console output.

Please help.

Best regards,
Mustaq Pradhan


execjs seems to have broken windows' wsh support at one point. Install
nodejs or add therubyracer gem.
