composer require dompdf/dompdf not install

Question

Your requirements could not be resolved to an installable set of packages. Problem 1 - laravel/framework is locked to version v7.28.4 and an update of this package was not requested. - laravel/framework v7.28.4 requires php ^7.2.5 -> your php version (8.0.0) does not satisfy that requirem

_your php version (8.0.0) does not satisfy that requirement_ — Alberto Sinigaglia, Jan 05 '21 at 18:52

dompdf above v1 and laravel 6,7,8 now support php 8, you just wrong dependencies version or operator.

Or operator in composer is |, so just change || to | in your composer.json, example:

"php": "^7.1 || ^8.0 ||^7.2.5",
"laravel/framework": "^8.0||^7.0",

to:

"php": "^7.1 | ^8.0 |^7.2.5",
"laravel/framework": "^8.0|^7.0",

But I think you need to define one, laravel 8 or 7.

And btw your php ^7.2.5 is wortless/will be ignored.

After update composer.json, don't forget to run composer update before install other depedency.
