Errors

Is there some trick—short of chowning /usr/lib/node_modules—that will stop these errors from occuring?

node.js
ubuntu
npm
sudo
node-modules

Solution

(feel free to use a path other than $HOME/npm)

Remove everything but npm from global node_modules folder (/usr/lib/node_modules)
$ mkdir "$HOME/npm"
$ npm config set prefix "$HOME/npm"
$ printf "NODE_PATH=$NODE_PATH:$HOME/npm/lib/node_modules\nPATH=$PATH:$HOME/npm:$HOME/npm/bin\n" >> ~/.bashrc && source ~/.bashrc
