In this Laravel tutorial, we will be addressing the error message “Your requirements could not be resolved to an installable set of packages.” This error typically occurs when the required packages’ versions are incompatible. This issue may arise when moving a Laravel project from one system to another, or when the PHP version required by the Maatwebsite/Excel package is not compatible with the PHP version required by the PhpOffice/PhpSpreadsheet package.
Let’s try to solve the error.
What exact issue?
Your requirements could not be resolved to an installable set of packages.
Your requirements could not be resolved to an installable set of packages. Problem 1 - maatwebsite/excel[3.1.28, ..., 3.1.30] require phpoffice/phpspreadsheet 1.16.* -> satisfiable by phpoffice/phpspreadsheet[1.16.0]. - maatwebsite/excel[3.1.31, ..., 3.1.x-dev] require phpoffice/phpspreadsheet ^1.18 -> satisfiable by phpoffice/phpspreadsheet[1.18.0, ..., 1.28.0]. - maatwebsite/excel 3.1.27 requires phpoffice/phpspreadsheet ^1.16 -> satisfiable by phpoffice/phpspreadsheet[1.16.0, ..., 1.28.0]. - maatwebsite/excel 3.1.26 requires phpoffice/phpspreadsheet ^1.15 -> satisfiable by phpoffice/phpspreadsheet[1.15.0, ..., 1.28.0]. - maatwebsite/excel[3.1.0, ..., 3.1.25] require php ^7.0 -> your php version (8.1.2) does not satisfy that requirement. - phpoffice/phpspreadsheet[1.15.0, ..., 1.28.0] require ext-gd * -> it is missing from your system. Install or enable PHP's gd extension. - Root composer.json requires maatwebsite/excel ^3.1 -> satisfiable by maatwebsite/excel[3.1.0, ..., 3.1.x-dev]. To enable extensions, verify that they are enabled in your .ini files: - C:\xampp\php\php.ini You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode. Alternatively, you can run Composer with `--ignore-platform-req=ext-gd` to temporarily ignore these required extensions. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
This error message indicates that there are conflicts between the required versions of packages needed for the project.
Specifically, the version of PHP required by maatwebsite/excel package is not compatible with the PHP version you have installed.
Additionally, the php-gd extension is missing which is required by phpoffice/phpspreadsheet package.
To resolve this issue, you can take the following steps:
- Upgrade your PHP version to meet the requirements of the maatwebsite/excel package. Alternatively, you can downgrade the maatwebsite/excel package to a version that is compatible with your current PHP version.
- Install or enable the php-gd extension.
- You can also run Composer with –ignore-platform-req=ext-gd to temporarily ignore the required extensions.
composer install --ignore-platform-req=ext-gd
composer update --ignore-platform-req=ext-gd
This option to allow upgrades, downgrades and removals for packages currently locked to specific versions.
