To completely uninstall node + npm is to do the following:

• go to /usr/local/lib and delete any node and `node_modules
• go to /usr/local/include and delete any node and node_modules directory
• if you installed with brew install node, then run brew uninstall node in your terminal
• check your Home directory for any local or lib or include folders, and delete any node or node_modules from there
• go to /usr/local/bin and delete any node executable

sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp /opt/local/bin/node /opt/local/include/node /opt/local/lib/node_modules
