How to install the nvm for node.js on ubuntu 12.04

Question

I try to install the nvm for my node.js . But I have to do export PYTHON=python2 .

What is this and how does it work?

I use Ubuntu 12.04 in a virtualbox. I can't get the nvm installed... more than two days this is keeping me awake... what did I do wrong?

You need to do export PYTHON=python2 only if python3 is set by default on your system.

First check the python version by running

> python --version
> Python 2.7.3

If it shows 3.xx then you should simply run this in this console before running installer eg.

export PYTHON=python2

then run installer

curl https://raw.github.com/creationix/nvm/master/install.sh | sh
#or
wget -qO- https://raw.github.com/creationix/nvm/master/install.sh | sh

See nvm docs link .
