Answer 1

In my case I tried everything that was listed above. I was using Laravel and Vagrant with 4GB of memory and a swap, with memory limit set to -1. I deleted the vendor/ and tried other PHP-versions. Finally, I managed it to work by running

vagrant up

And then composer install worked again as usual.
