Easy, type this commands:

rm -rf vendor/

rm -rf composer.lock

Answer 4

you can use the following to check your free (swap) memory

free -m

total used free shared buffers cached

Mem: 2048 357 1690 0 0 237
-/+ buffers/cache: 119 1928
Swap: 0 0 0

To enable the swap you can use for example:

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

Answer 5

edit php.ini file and increase memory_limit value.

memory_limit=1G

will solve this issue.

Answer 6

I tried by just deleting the vendor folder and composer.lock file and then i run the command composer clear-cache and then composer install. So it working without any error.
