My version of node is always v0.6.1-pre even after I install brew node and NVM install v0.6.19.
My node version is:
On Mavericks I install it from the node pkg (from nodejs site) and I uninstall it so I can re-install using brew. I only run 4 commands in the terminal:
sudo rm -rf /usr/local/lib/node_modules/npm/
brew uninstall node
brew doctor
brew cleanup --prune-prefix
If there is still a node installation, repeat step 2. After all is ok, I install using brew install node
