- Firstly you need to download the latest version of NodeJS at the time of writing this the version is v.0.4.2. This can be found at http://www.nodejs.org
- Extract this to an area of your disk.
- Enter Terminal. (I normally type this in the search box to find quickly).
- Navigate to your nodeJS directory. cd /MyNodeJs/ <Press Return>
- ./Configure <Press Return>
- make <Press Return>
- sudo make install <Press Return>
Voila you should a successful install of NodeJS.
