The answer's right in the message
the requested PHP extension intl is missing from your system
You need to install PHP's intl extension. apt-get install php-intl, brew install phpXX-intl, or whatever installation method your system is using will do it. Or if you're compiling PHP yourself, pass the --enable-intl argument into your configuration command.
@mbabker yea, thanks, i've installed this extension and installation was successful! thank you!
I have the same problem, but I've installed intl extension. What is the problem?
@VladyslavDP, i think you should watch what another extensions you need to install, may be it is not just intl.
