Issue

I have tried to install the package of phpspreadsheet for both way for github and through composer also but I am unable to install In composer i am trying these command :- composer require phpoffice/phpspreadsheet but its not working It's basically show these type of error:- [InvalidArgumentException] Package phpoffice/phpspreadsheet has requirements incompatible with your PHP version, PHP extensions and Composer v ersion: - phpoffice/phpspreadsheet 1.19.0 requires ext-gd * but it is not present. And when i am trying directly for github code its files is not in proper way as the requriement git hub link:- https://github.com/PHPOffice/PhpSpreadsheet

Solution

phpoffice/phpspreadsheet v1.19.0 requires php: ^7.3 || ^8.0

1. Check your installed PHP version by running this command php -v. Make sure it's greater or equal to 7.3.

2. Secondly, make sure that the PHP version declaration in the composer.json file is also greater or equal to 7.3. I.e:

        "php": "^7.3 || ^8.0",

• If in case your application has dependencies that aren't compatible with PHP version >= 7.3, you may want to install a lower version of phpspreadsheet i.e composer require phpoffice/phpspreadsheet "^1.8.0" (requires php: "^5.6|^7.0") instead of adjusting the PHP version in the file composer.json.

3. In addition, if you're using xampp, make sure these extensions are enabled in the file C:\xampp\php\php.ini before attempting to install the library.
   extension=mbstring
extension=fileinfo
extension=gd

Installation

composer require phpoffice/phpspreadsheet "^1.19.0"
