Please install intl extension - this is a required component.

Hi there, I installed intl extension but still receiving this error.

[cijagani]

intl extension required for php cli also.

[cijagani]

can you verify it?

I am using ubuntu 20.04 you shall install php7.4-intl by running the following command:
sudo apt install php7.4-intl

Please install intl extension - this is a required component.

I had this issue using XAMPP on Windows 10.

[himanshupatel1902]

Issue resolved in Ubuntu

edit php.ini file located at
/etc/php/7.4/apache2/php.ini

remove ; before "extension=intl"

means
;extension=intl

should become

extension=intl

[DanielTheGeek]

Above is what I now get after enabling intl in PHP.ini

Please change CI_ENVIRONMENT to development in your .env file.

That worked fine but another thing that worked too was setting up a virtual host configuration for my local domain and adding it into the hosts file. Now everything works fine at mydomain.local. Thank you very much!

try to change in /system/Codeignater.php line 184
locale_set_default($this->config->defaultLocale ?? 'en');

become:

if( function_exists('locale_set_default' ) ) :
    locale_set_default($this->config->defaultLocale ?? 'en');
    endif;
