eeds requires the library "laminas/laminas-feed", even though library is present in the vendor folder

This could be a Composer issue. I don't know a lot about fixing Composer related problems. One thing that helped me sometimes when I faced a Composer related issue like this, is deleting the vendor library ("laminas" in this case) and the module directory ("feeds" in this case) and then try again with either composer install or composer update drupal/feeds.

Note that on the automated test runner, Feeds installs fine with laminas/laminas-feed (2.23.0), so that's why I think it is more likely to be a Composer issue than a Feeds issue. See https://git.drupalcode.org/project/feeds/-/jobs/3183360

To be certain, the "laminas/laminas-feed" is installed the site's vendor directory? Thus in site/vendor, not in site/web/modules/contrib/feeds/vendor?

Indeed thank you @megachriz it was a composer issue, and I was able to uninstall remove the vendor folder and reinstalled just fine.

Much appreciate your comment that identified where I needed to look!

having the same issue, everything seems to install fine through composer ( Installing laminas/laminas-stdlib (3.20.0): Extracting archive), but when i try to activate feeds i get,
error -feeds requires the library "laminas/laminas-feed". You can install it with Composer or by using the Ludwig module.
tried deleting Laminas and feeds folders and reinstalling with composer but no change. any ideas?

That's a pity that you run into this, but I don't know why that happens. If you are on Drupal Slack, maybe could ask in the #composer channel?
