pip install out of memory kill process

Quick fix if you are running a low memory server or vps. Extend your RAM by adding a swap file.

A swap file is a file stored on the computer hard drive that is used as a temporary location to store information that is not currently being used by the computer RAM. By using a swap file a computer has the ability to use more memory than what is physically installed in the server.

In Short:( for adding 500Mb of RAM we set 524288)

1. Login as root: su - or execute the commands with sudo in front
2. dd if=/dev/zero of=/swapfile1 bs=1024 count=524288
3. mkswap /swapfile1
4. chown root:root /swapfile1
5. chmod 0600 /swapfile1
6. swapon /swapfile1

Now the swap file will be activated temporarily, but will be gone after reboot.You should have enough RAM for your installing process

To Remove the File:

1. swapoff -v /swapfile1
2. rm /swapfile1
