maatwebsite/excel[3.1.0, ..., 3.1.25] require php ^7.0 -> your php version (8.2.13) does not satisfy that requirement.

When installing this package, the following problem occurs. Does it due to the dependent package? Is it solvable by downgrading PHP only?

maatwebsite/excel[3.1.0, ..., 3.1.25] require php ^7.0 -> your php version (8.2.13) does not satisfy that requirement.

No, it definitely supports PHP8.2 in a higher version (see the repo: https://github.com/SpartnerNL/Laravel-Excel/blob/f3cce8310b94b4e5716a71da58440ae81c7afe24/composer.json#L24)

So the install is probably blocked by something else.

Well, the following is the full error message after running composer require psr/simple-cache:^2.0 pxlrbt/filament-excel, if this is the correct installation command.

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.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require pxlrbt/filament-excel:*" to figure out if any version is installable, or "composer require pxlrbt/filament-excel:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
