I have a problem installing symfony 3.1 in php7, nginx and ubuntu 16.04, i have this error:

intl ICU version installed on your system is outdated (55.1) and does not match the ICU data bundled with Symfony (57.1) To get the latest internationalization data upgrade the ICU system package and the intl PHP extension.

How can i solve this issue? can i change symfony and use IC 55.1 instead of ICU 57.1?

I presume you get this when you run:

php bin/symfony_requirements

This is just a warning and you can safely ignore the message. I've response to similar questions on this. See this URL for more details:

  • i was running the config.php , i run the php bin/symfony_requirements, and you are right is an optional recommendation. thank you . – Andres Sep 07 '16 at 21:13
  • I know that it's optional, but if one wanted to upgrade PHP Intl ICU to 57.1, do you know how that is done? – user658182 Feb 10 '17 at 17:38
  • No idea on how to install ICU 57.1 properly. I've tried a number of things and no luck. Probably best to ignore the warning message. – Alvin Bunk Feb 10 '17 at 21:46

To install ICU 57.1 run:

curl -sS -o /tmp/icu.tar.gz -L http://download.icu-project.org/files/icu4c/57.1/icu4c-57_1-src.tgz && tar -zxf /tmp/icu.tar.gz -C /tmp && cd /tmp/icu/source && ./configure --prefix=/usr/local && make && make install
