[FIXED] error installing a package " Installation failed, reverting ./composer.json and ./composer.lock to their original content. "

Issue

i am trying to install spatie/sitemap package on my laravel package but i keep getting this error i don't know what's the problem :

Your requirements could not be resolved to an installable set of packages.

Problem 1

    - spatie/crawler[5.0.2, ..., v5.x-dev] require guzzlehttp/psr7 ^1.4 -> found guzzlehttp/psr7[1.4.0, ..., 1.x-dev] but the package is fixed to 2.0.0 
(lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - spatie/crawler[5.0.0, ..., 5.0.1] require php ^7.4 -> your php version (8.0.1) does not satisfy that requirement.
    - spatie/crawler 7.0.0 requires guzzlehttp/psr7 ^1.8 -> found guzzlehttp/psr7[1.8.0, 1.8.1, 1.8.2, 1.x-dev] but the package is fixed to 2.0.0 (lock 
file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - spatie/laravel-sitemap 6.0.4 requires spatie/crawler ^5.0 || ^7.0 -> satisfiable by spatie/crawler[5.0.0, 5.0.1, 5.0.2, v5.x-dev, 7.0.0].
    - Root composer.json requires spatie/laravel-sitemap 6.0.4 -> satisfiable by spatie/laravel-sitemap[6.0.4].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

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

i tried to specify the version of the package and used the latest one 6.0.4 but it didn't work too and i have no idea what to do !! please some help .

UPDATE

}

Solution

i got it to work by installing and enabling php exif, first i installed a php exif package through composer and then i enabled it from php.ini and it worked perfectly .
