Hello,
Installing Laravel 5.7 app on ubunutu 16 under LEMP/AWS I got error :
# composer install
Loading composer repositories with package information
Updating dependencies (including require-dev)
- Installing symfony/polyfill-ctype (v1.11.0)
Downloading: 100%
The following exception is caused by a lack of memory and not having swap configured
Check https://getcomposer.org/doc/articles/troubleshooting.md#proc-open-fork-failed-errors for details

Also strange thing that I have installed my applications in ubuntu 18 under Digital Ocean with the same memory quantity.
on AWS Ubuntu 16:
# lsb_release -d; uname -r; uname -i
Description: Ubuntu 16.04.6 LTS
4.4.0-1084-aws
x86_64
# free
total used free shared buff/cache available
Mem: 1014384 48724 856564 700 109096 824368
Swap: 1048572 264404 784168
on Digital Ocean Ubuntu 18(this app works ok):
# lsb_release -d; uname -r; uname -i
Description: Ubuntu 18.04.1 LTS
4.15.0-47-generic
x86_64
# free
total used free shared buff/cache available
Mem: 1009156 324640 109012 52520 575504 473160
Swap: 1048572 357888 690684
Can the reason of error on AWS Ubuntu 16 that something is not configured properly?
Though I installed and configured both servers on AWS and Digital Ocean, maybe I missed something on AWS Ubuntu 16 ?
Thanks!
