Pip install killed - out of memory - how to get around it?

Try adding swap space to your VPS. That will let you use free disk space as memory

This has been reported already on github

Below are some good thread on how to solve the issue

In Summary, below are the two options:

1. Try with --no-cache-dir, which unfortunately has not helped you

2. Increase the swap space

$ create swap file of 512 MB
dd if=/dev/zero of=/swapfile bs=1024 count=524288

$ modify permissions
chown root:root /swapfile
chmod 0600 /swapfile

$ setup swap area
mkswap /swapfile

$ turn swap on
swapon /swapfile
