'Composer fails with kylekatarnls/update-helper on new homestead

I have installed a homestead on a new computer. I have pulled my code (which is working on my other computer as well as the server). My project is made in Laravel 5.7

When I do a composer require to get everything in place to, i get this error: Plugin kylekatarnls/update-helper could not be initialized, class not found

I have tried composer clear:cache, reinstalled the homestead-7 box. Non of it has worked. I still get the same error

But no matter what I get the same error

composer require

I tried 

composer global require kylekatarnls/update-helper

then it worked

Solution 2:[2]

Install without plugins if they're not necessary for you.

composer install --no-plugins

I found that actually upgrading from version 8.0.0 of the vagrant box to 8.0.1 solved this for me So in the homestead folder run

vagrant box update

Solution 4:[4]

I assume the lateste laravel / homestead box is incompatible with laravel 5.7.*. In the homestead/script/homestead.rb I changed line 21 to: config.vm.box_version = settings['version'] ||= '= 7.1.0'

thereby I forced my homestead to only use box v. 7.1.0 (as on my other computer).

vagrant up
vagrant ssh
composer require

worked like a charm.

I think you should try to disable any configuration of IP6 for your NICs. Yesterday (July, 4th), I had the same issue and I tried a lot of things. Nothing! but ... suddenly I tried to check out more information about the composer's issues and ... Eureka! sometimes the Composer does not work with any IP6 config. You can read more about it here: https://getcomposer.org/doc/articles/troubleshooting.md

I upgraded composer to its latest version and it solved! In order to upgrade composer, first go to composer directory, then use following command:

php composer.phar self-update
