Your requirements could not be resolved to an installable set of packages. Problem 1 - league/flysystem[2.1.0, ..., 2.x-dev] require league/mime-type-detection ^1.0.0 -> satisfiable by league/mime-type-detection[1.0.0, ..., 1.14.0]. - league/flysystem[3.0.0, ..., 3.x-dev] require php ^8.0.2 -> your php version (7.4.33) does not satisfy that requirement. - league/mime-type-detection[1.0.0, ..., 1.14.0] require ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension. - Root composer.json requires league/flysystem ^2.1|^3.0 -> satisfiable by league/flysystem[2.1.0, ..., 2.x-dev, 3.0.0, ..., 3.x-dev]. To enable extensions, verify that they are enabled in your .ini files: - C:\tools\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-fileinfo` to temporarily ignore these required extensions.
