Solution: Remove node and npm modules completely and reinstall them

Completely Uninstall Node.js from Mac OS X

The following is the best way to completely uninstall node + npm:

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
You may need to do the additional instructions as well:

sudo rm /usr/local/bin/npm
sudo rm /usr/local/share/man/man1/node.1
sudo rm /usr/local/lib/dtrace/node.d
sudo rm -rf ~/.npm
sudo rm -rf ~/.node-gyp
sudo rm /opt/local/bin/node
sudo rm /opt/local/include/node
sudo rm -rf /opt/local/lib/node_modules
