I have read it is best to use composer for installign modules. So I am trying
php8.0 /usr/local/bin/composer require drupal/google_analytics
Using version ^3.1 for drupal/google_analytics
./composer.json has been updated
Running composer update drupal/google_analytics
> Drupal\Composer\Composer::ensureComposerVersion
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.
Problem 1
- drupal/google_analytics[dev-3.x, 3.1.0] require drupal/core ^8.8.6|^9.0 -> satisfiable by drupal/core[8.8.6, ..., 8.9.x-dev, 9.0.0-alpha1, ..., 9.3.x-dev] from composer repo (https://repo.packagist.org) but drupal/core[dev-main] from path repo (core) has higher repository priority. The packages with higher priority do not match your constraint and are therefore not installable. See https://getcomposer.org/repoprio for details and assistance.
- drupal/google_analytics 3.x-dev is an alias of drupal/google_analytics dev-3.x and thus requires it to be installed too.
- Root composer.json requires drupal/google_analytics ^3.1 -> satisfiable by drupal/google_analytics[3.1.0, 3.x-dev (alias of dev-3.x)].
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.
How to understand those errors? Looks like it requires drupal 8 or 9 but i have 9 so why there is a problem? I see there is mentioned priorities, I have read https://getcomposer.org/doc/articles/repository-priorities.md but I do not get what I need to fix for it to work. Can you tell?

Answer 1

Deleted vendor directory. Ran composer install. Noticed message after installation
drupal/drupal: This package is meant for core development,
and not intended to be used for production sites.
See: https://www.drupal.org/node/3082474
Packages already clean.
In the link I saw composer command to create new project, so I modified it to this one and tried:
composer -n create-project drupal/recommended-project:* drupal3
then followed installation steps https://www.drupal.org/docs/installing-drupal
and then tried installing google analytics - and it went without problems.
