getaddrinfo ENOTFOUND localhost -> This error means localhost can't be resolved. This is likely an issue with your /etc/hosts file. Please see this article for fixing it on macOS: http://osxdaily.com/2014/04/12/restore-original-hosts-file-mac/

Basically, /etc/hosts must contain the following entries:

127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost

Add below lines to your /etc/hosts file

##
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0     localhost
