System prep for app developers 1: Setting up your command-line interface

Thanks Argyris Gerogiannis, I was struggling through this installation process and had tried several workarounds with no luck - your advise perfectly worked for me.

Thanks Argyris, that information should be added to the official documentation! In addition, I also had to install the zlib1g-dev package.

I was trying to install zendesk_apps_tools in windows 10 linux subsystem with errors concerning missing packages.

After some reading to my logs and installing the below it worked like a charm:

1. ruby-dev
2. gcc
3. make
4. g++
5. zlibc
6. zlib1g

The packages were missing from my default installation in ubuntu windows
