Installing Node

Using nvm (Node Version Manager) will allow you to have multiple versions of Node on your machine. More importantly, it will prevent you from having to use sudo when installing using npm install.

1. Run the following commmand anywhere to install nvm:

   git clone https://github.com/creationix/nvm.git ~/.nvm && cd ~/.nvm && git checkout `git describe --abbrev=0 --tags`

2. Enable nvm on your system by edit the .bashrc or .profile file:

   vi ~/.bashrc

3. Paste the following into your open file. This will initialize the nvm environment every time your terminal loads:

   source ~/.nvm/nvm.sh

4. Either restart your terminal to make your .bashrc reload, or just use the source command:

   source ~/.bashrc

5. Use nvm to install node:

   nvm install 0.10

6. Tell nvm which version of node to default to:

   nvm use 0.10
   nvm alias default 0.10

   Note: You can use nvm ls-remote to see the most current releases of node.

7. To see a list of all the node versions you have installed:

   nvm ls

For advanced users: To make your current node and npm available for all the users on your machine (think VPS), run the following command:

n=$(which node);n=${n%/bin/node}; chmod -R 755 $n/bin/*; sudo cp -r $n/{bin,lib,share} /usr/local

This will take your current locally visible binaries and move them to /usr/local for everyone to see.
