I'm following this link to install this PHP extension but I'm stuck in the middle.
When I try to run this command pecl install intl I get this message:
Specify where ICU libraries and headers can be found [DEFAULT] :
And I don't know where the ICU libraries are located.
If I press Enter I get this error:
configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works.
ERROR: `/private/tmp/pear/install/intl/configure --with-php-config=/usr/bin/php-config --with-icu-dir=DEFAULT' failed
How can I locate the correct path of ICU libraries ? I'm using High Sierra and MAMP with PHP version 7.1
ICU stands for ICU - International Components for Unicode
Install it with brew
brew update
brew search icu # returns 'icu4c'
brew install icu4c
OR
Install it with pecl
sudo pecl update-channels
sudo pecl install intl
