How to setup Appium on Ubuntu 14.04- 32 bit?

I am trying to install Appium on Ubuntu 14.04 32 bit system.
I followed the following stack overflow link “How to setup Appium in Ubuntu for android” to install it.

I have installed Node.js and it also asked for installing grunt-cli and then i installed Appium.
But whenever I try to run Appium, it gives me an error No such file or directory.

install using linux brew, and follow instructions as per appium documentations.
