When you run hexo g on any web instances, like on AWS or Azure, you might get the following error:
(node:3568) ExperimentalWarning: The fs.promises API is experimental
INFO Validating config
INFO Start processing
Killed
Solution:
This might be caused by running out of memory, try to run the following command:
free -m
dd if=/dev/zero of=/swap bs=4096 count=1572864
mkswap /swap
swapon /swap
echo "LABEL=SWAP-sda /swap swap swap defaults 0 0" >> /etc/fstab
