Aggregator settings error after installing on D10

Did you install using composer?

I didn't use composer to install it. The Drupal site is hosted on Hostinger. I installed Aggregator by Add new module of Extent at the site backend.

This module has third party dependencies and can only be installed with composer

I tried using composer to install Aggregator via SSH:
composer2 require "drupal/aggregator:^2.2"
But I got the message: No security vulnerability advisories found

It cannot complete installation. What's wrong?

It is difficult to debug what's wrong in your environment

Can you confirm your project has a root composer.json file and started from a composer template?

Yes, I can see composer.json under the root.
By the way, my Drupal 10 site is on a subdomain. I went to the subdomain folder and use composer:
composer2 require "drupal/aggregator:^2.2"

Anything wrong?

You need to run composer commands in the same folder as the composer.json file

Can you share your composer.json file?

I don't know how to share composer.json file. You can tell me how to.

My sites hosted on Hostinger. I logged in to SSH and I can see 2 folders in the root:
domains
public_html
I can find composer.json under the public_html
My Drupal 10 site is installed to the subdomain m.helan123.com, I can go to the folder:
domains/helan123.com/public_html/m

where do I run composer to install the Aggregator module?

It sounds like you need to run it in the public_html directory. Run composer show there and see if it lists drupal/core and other modules. If it does, then that's where you should require Aggregator.

Run composer2 show in the public_html(not a root of Drupal), I can see it lists:
...
drupal/core 10.2.6
drupal/core-composer-scaffold 10.2.6
drupal/core-project-message 10.2.6
drupal/core-recommended 10.2.6
drupal/core-vendor-hardening 10.2.6
...

But the public_html directory is not the root of my Drupal site where I want to install modules. Is it possible to run composer here?

I have multiple Drupal sites hosted in the same Hostinger account, they are in other directories like:
domains/drupalsite1.com/public_html
domains/drupalsite2.com/public_html
domains/drupalsite2.com/public_html/subsite

Now I want install Aggregator to the subsite:
domains/helan123.com/public_html/m

Where do I run composer to install the Aggregator module to the specific site?

You can run it anywhere there is a composer.json file and the output of composer show includes Drupal core.

Note that if you run it in the public html folder, the code might be available to install on all the domains, but you don't have to enable the module in all of them. Composer require just downloads all the needed files and libraries

I run composer in the public_html:
composer2 require "drupal/aggregator:^2.2"

I can see the message:
...
In Filesystem.php line 284:
Could not delete /home/.../public_html/sites/default/default.services.yml:
...

Is it something wrong?

It is most likely file permissions on the sites/default folder

Okay, I will update the file permissions and try it again.

I don't like the Aggregator module is downloaded to multiple Drupal sites that don't need this module. If install the Aggregator module to the specific site, Is there any solution?

Should I copy composer.json file to the Drupal directory and run composer there?

Aggregator was part of core until D10
It was on disk on many sites without being installed

Yes, Aggregator is in core before D10 that's easy for me to use without installing and updating myself. I have several old version Drupal sites with Aggregator. Now it's difficulty to install with D10. I like using this module and maybe often need to install and update it. I'm a Drupal fan use use it from D4 to D10. I'm not a techical of Drupal, So I need find a good solution.

Now I have 2 sites of D10 with different domains, and more new Drupal sites in the future that share the composer system on Hostinger. But I need using composer to install Aggregator and other extent modules for a single site.

So I want to know where to run:
composer2 require "drupal/aggregator:^2.2"

It can only install the module to the site:
domains/helan123.com/public_html/m

Is there any solution?

I copy the content of composer.json here. I see the line "url": "https://packages.drupal.org/8". It seems for D8.
Anything wrong to use it for D10?

You should run the command in public_html
Your composer.json looks it already has aggregator in it?

Yes, I have run composer in public_html:
composer2 require "drupal/aggregator:^2.2"

I checked it at the site backend. The Aggregator module is available in every D10 site (the code is available to install on all the domains). I can enable Aggregator of the D10 site in the root public_html. It looks that composer works well. But I don't need Aggregator for this site.

Then For the site (m.helan123.com) that I need install Aggregator, I go to Extent/Web services, check Aggregator and click on Install. The module cannot be enabled but I get the message:
Error message
Unable to install Aggregator, filter.format.aggregator_html already exists in active configuration.

What's wrong?

That sounds like carry over from a previous install that failed.

If you visit admin -> config -> content authoring -> input formats - can you delte the aggregator html format and try again?

If not, do you have access to drush?

If so, can you run `drush cdel filter.format.aggregator_html` and then try again to reinstall

I use composer to install drush in public_html:
composer require --dev drush/drush

Execute the following command to check:
./vendor/bin/drush --version
Drush Commandline Tool 12.5.2.0

I ran drush but got commad not found:
drush cdel filter.format.aggregator_html
-bash: drush: command not found

drush doesn't work?

Does the same thing happen if you run vendor/bin/drush cdel filter.format.aggregator_html?

Okay I will try running vendor/bin/drush cdel filter.format.aggregator_html

But I don't understand why run drush to delete somthing in public_html (root)? because no problem to enable Aggregator in this site.

Should I install drush again to the site (domains/helan123.com/public_html/m) that has the problem of Aggregator?

Where to run drush?

Please try to delete from the UI first

Do you mean to uninstall Aggregator from the UI?

The problem is that Aggregator cannot be enabled, I can't find it in the Uninstall list of the UI.

No, the filter format - see comment 24

I forgot to tell you that I had deleted the aggregator html format already but the problem still couldn't be solved. Then I tried thrush.

Should I install drush again to the site (domains/helan123.com/public_html/m) that has the problem of Aggregator?

If you've deleted the filter format, you should now be able to enable aggregator module

No. Still unable to install it. See the screenshots attached.
Error message
Unable to install Aggregator, filter.format.aggregator_html already exists in active configuration.

Seems like it wasn't deleted then?

The Aggregator HTML format had been deleted, but it's still not possible to enable Aggregator.
