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?

Accepted Answer

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.x.x 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.
