Requirements
The server requirements for Craft Commerce are the same as Craft 3.5 as well as PHP’s SOAP extension.
# PHP Package Dependencies
Craft Commerce uses the following PHP packages. Please see their documentation for any additional requirements.
- craftcms/cms ^3.5.4
- dompdf/dompdf ~0.8.3 (recommends GD and IMagick)*
- moneyphp/money ^3.2.1
- ibericode/vat ^1.1.2
# Dompdf
In strictly following Craft’s server requirements, Commerce requires a version of Dompdf that’s compatible with PHP 7.0 but results in errors with PHP 7.4.
You can resolve by updating your project’s composer.json platform requirement to PHP 7.1 or greater:
// ...
"config": {
"optimize-autoloader": true,
"platform": {
"php": "7.1"
}
}
// ...
Running composer update will install Dompdf 0.8.4+.
