As if we need more answers here, but anyway..

Sindre Sorus has a guide Install npm packages globally without sudo on OS X and Linux outlining how to cleanly install without messing with permissions:

Here is a way to install packages globally for a given user.

1. Create a directory for your global packages

   mkdir "${HOME}/.npm-packages"
   

2. Reference this directory for future usage in your .bashrc/.zshrc:

   NPM_PACKAGES="${HOME}/.npm-packages"
   

3. Indicate to npm where to store your globally installed package. In your $HOME/.npmrc file add:

   prefix=${HOME}/.npm-packages
   

4. Ensure node will find them. Add the following to your .bashrc/.zshrc:

   NODE_PATH="$NPM_PACKAGES/lib/node_modules:$NODE_PATH"
   

5. Ensure you'll find installed binaries and man pages. Add the following to your .bashrc/.zshrc:

   PATH="$NPM_PACKAGES/bin:$PATH"
   # Unset manpath so we can inherit from /etc/manpath via the `manpath`
   # command
   unset MANPATH # delete if you already modified MANPATH elsewhere in your config
   MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
