I am getting the error
Fatal error: Class 'IntlDateFormatter' not found in Magento2 after installation.
Just need to clear comment before this line in
I had same issue but in my case
intl was installed and loaded checking
brew install icu4c resolved issue on my Mac. I'm using php 5.6.30 by the way.
sudo apt-get install php7.0-intl did the trick for me on Ubuntu 18.04.
(That's with this PPA repo containing a backport of PHP
sudo add-apt-repository ppa:ondrej/php.)
