I am getting this error with Laravel 9, I have PHP 8.1.7 installed
Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.1.0".
I can see other have asked the question, bit non of the solutions seem to be working

Answer 1

TIPS
Add this lines in composer.json file:
{
"config": {
"platform-check": false
}
}
Or set the version:
{
"config": {
"platform": {
"php": "7.1.0"
}
}
}
And run composer dump-autoload

Answer 2

I had the same problem and it was because I configured a version of PHP 8.1 on the command-line while I kept the PHP module at 8.0.
So PHP_VERSION_ID gave me 80020, while php -v gave me 8.1.7.
It reminded me to reconfigure the PHP Module to PHP version 8.1:
sudo a2dismod php8.0
sudo a2enmod php8.1
sudo systemctl restart apache2
And then everything worked like intended.
Reference:
phpinfo() and php -v shows different version of PHP

Answer 3

If #eril answer did not help you by disabling old PHP version
sudo a2dismod php8.0
sudo a2enmod php8.1
sudo systemctl restart apache2
also check composer using a correct version of PHP
composer -vvv about 2>&1 | grep "PHP"
if composer about already shows a correct version of PHP,then check to see the real PHP binary path that composer is using by putting PHP_BINARY inside vendor/composer/platform_check.php like this:
if (!(PHP_VERSION_ID >= 80100)) {
$issues[] = 'You are running ' . PHP_VERSION . ' located at: ' . PHP_BINARY;
}
in my case, an old version of php-fpm was enabled.
a2disconf php8.0-fpm
a2enconf php8.1-fpm
sudo systemctl restart apache2

Answer 4

If you install composer globally, just run composer global update. It will solve your problem.

Answer 5

Open your composer.json and check where the 'require' block says 'php'. It has an expression that can put a constraint on the PHP version or version range that is allowed for all of your projects' dependencies.
A good value would be to use the one below. Change it and run composer update afterwards.
"require": {
"php": "^8.0|^8.1",
Contrary to the composer.json which laravel 9 ships with:
"require": {
"php": "^8.0.2",
(see laravel 9 composer.json in the official repository: https://github.com/laravel/framework/blob/9.x/composer.json)

Answer 6

Don't change any thing in your application. In your shard hosting, go to cPanel and find/search Multi PHP Manager. Select your domain or sub domain (whatever you are working with), from dropdown list select PHP 8.1 and apply.
Now find/search PHP Selector and for Current PHP Version select 8.1.
in the same window go to Extensions and enable pdo_mysql.
You are good to go.

Answer 7

Your Composer dependencies require a PHP version ">= 8.1.0"
I had this same issue while I downgraded my php to v7.4 from 8.1. I somehow messed up with php7.4-fpm mod. However, when I again tried to upgrade my php v8.1 composer started to complain about that error.
I simply removed my both php versions that's 7.4 and 8.1 and re-installed only 8.1, which fixed my issue.
To remove, here are the steps I followed....
sudo apt-get purge php8.*
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php8.1
and then finally,
sudo service apache2 restart

Answer 8

If you are simply using git to version your Composer dependencies for a deployment, consider the --ignore-platform-reqs flag.
For more info, see Options at https://getcomposer.org/doc/03-cli.md#install-i
composer update --dry-run --ignore-platform-reqs
--ignore-platform-reqs: ignore all platform requirements (php, hhvm, lib-* and ext-*) and force the installation even if the local machine does not fulfill these. See also the platform config option.

Answer 9

If you are operating on nginx server, It's likely the php-fpm8.1 is not active.
Try to:
sudo systemctl status php-fpm8.1.service
Depends on the status of the php-fpm version, you can act, and if it's stopped, you may want to do the following:
sudo systemctl enable php-fpm8.1.service
sudo systemctl start php-fpm8.1.service
Then double-check the status, and if it's active. You're good to go.
Note: This applies to any php-fpm version, not just 8.1.
Hope this help!

Answer 10

if you use XAMPP, check that the PHP version of your XAMPP is the correct one (the same one you have on your computer). Otherwise, download and install the correct version of XAMPP

Answer 11

Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.1.0".
I faced the same problem.
Just go to Cpanel.
Then PHP Selector
and finally, change PHP version

Answer 12

If you are in the process of upgrading Laravel versions and you switch to the version which requires PHP8 (8 or 9 cant remember)
And you also switch PHP versions,
you need to restart your
php artisan serve

Answer 13

in my case everything is fine
composer.json is fine
php 8.1 is installed
I am using nginx I restart nginx but I found that my configuration is wrong it looks like this
location ~ \.php$ {
fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
}
so the correct configuration is
location ~ \.php$ {
fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
}
Hope this will help someone

Answer 14

I had the exact issue.
I added the line phpversion() and found that the version was different from what was set for my apache.
I enabled the php8.1-fpm with this command:
sudo a2enconf php8.1-fpm
After restarting Apache I got it working.

Answer 15

It's just until I find how to solve it but it's working
So that's what i've done :
download php 8.1.9 (nts)
extract it in bin/php/ (i use Laragon)
move php 7.14.19 in a new folder(just for preventing)
and rename my php 8 folder to php 7 folder name
it's still working
Just find the php folder of your server
