composer require phpoffice/phpspreadsheet don’t work

initially, I needed a library that will help me upload data to Excel, found this library and then there was a problem

i try to install composer require phpoffice/phpspreadsheet but i have problem

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - The requested PHP extension ext-spltype * is missing from your system. Install or enable PHP's spltype extension.


Installation failed, reverting ./composer.json to its original content.

I don’t understand where the error comes from, because there is a dependency “ext-spltype”: “*” in my composer.json

this is my composer.json

i also try to install sudo pecl install SPL_Types , but i have error

Answer

I’m using Ubuntu 18.04 with Apache. Using the script from here works.

sudo apt-get install libpcre3-dev php5-dev php-pear -y
sudo pecl install SPL_Types
echo extension=spl_types.so | sudo tee /etc/php5/mods-available/spl_types.ini
sudo php5enmod spl_types
sudo service apache2 reload
