@Sinnbeck May I ask you a question. I was having similar problems of composer not being able to update. I.e. Error "Root composer.json requires php ^7.3 but your php version (8.0.0) does not satisfy that requirement" You referred us to this link: https://github.com/laravel/framework/blob/6.x/composer.json#L18 I copied your setup and banged it into my composer.json and it now works. Can you explain what this did. Did it put in correct files that were missing. Apol. Newbie.

@muazzamazaz Yeah. Check each version and you will find that it is only implemented in laravel 9 (return type of bool)

@Evaristo , this is php version issue, you probably have some composer dependencies that doesn’t work properly in new php version so you need to :

Delete vendor directory
downgrade you php version (I suggest 7.4) 3.Run "composer update"

I had the same problem. I switched back to PHP 7.4 and ran composer update and everything worked smoothly! To switch between PHP versions: $sudo update-alternatives --config php

select the one that you want (here 7.4 works), If you're using nginx: $sudo service nginx restart $sudo service php7.4-fpm restart $sudo service php8.1-fpm restart

Now run: $composer update It should work fine!

After I updated Laravel to 7 from 6, I again updated from Laravel 7 to 8 (using upgrade guide from Laravel documentation). After this I again switched back to PHP 8.1 and then ran composer update again and everything was fine!

I did the following and it worked fine:

-- Open composer.json file and change php version to something like this: "php": "^7.3|^8.1"

-- Then run composer update

Hope that help

@masoodanwar85 Thanks bro. This helped me too.

Don't understand why this worked though. Do you?

I had pulled in a package and it worked fine while being in a docker environment. Then one day it stopped working and then your solution fixed it. Curious what the reason is.

I believe this happened to you because you opened PHPStorm while your local server was let's say on PHP8.1, you then changed the version of your PHP server to 7.4 and hoped PHP storm would pick on it, but it does not.

What I do in this case is always set the server to the right PHP version and then open PHP storm(if you use such IDE).

Always make sure that PHP storms points to the correct PHP paths or your console will struggle finding the set PHP.

PHP Version issue causes this . To check your PHP version . Try to refresh your environment variable from your command line and try once again.

I got the same issue after moving my project from a local Xampp with PHP 8.0.* to an IIS server where I had PHP 8.1.*. Switching it from PHP 8.1 to 8.0 solved it for me. Ensure you change the PHP paths EVERYWHERE necessary - in environment variables, FastCGI settings, Project path etc.

{ "require": { "php": "^7.2.5|^8.0.13", ... "laravel/framework": "^8", }, config:{ "platform": { "php":"7.4" } } }

then run composer install

just copy this file content https://github.com/laravel/laravel/blob/10.x/composer.json then delete your composer.json 's content and paste what you copy in composer.json then save run composer update

I got this error whilre running my web app ( using laravel with php7.3 ) using homestead. It took me so long to finally found out that the error I got was from running php8 in the host machine.

So I change the php version from the host machine to 7.3 as well.

Now the problem has all gone.

I dont know why but apparently, the php in the host machine does affect the php in the homesteead as well.

So you need to make sure the php version in homestead is the same as the host machine.

In composer.json file in script object define PHP version like @php7.4

"scripts": { "post-root-package-install": [ "@php7.4 -r "file_exists('.env') || copy('.env.example', '.env');"" ], "post-create-project-cmd": [ "@php7.4 artisan key:generate --ansi" ], "post-autoload-dump": [ "Illuminate\Foundation\ComposerScripts::postAutoloadDump", "@php7.4 artisan package:discover --ansi" ] },
