Cryptic error messages with npm and node

Question

I'm following facebook's tutorial on getting started with React Native (https://facebook.github.io/react-native/docs/tutorial.html#hello-world), but I can't get the react-native-cli to install. Any help interpreting the error messages? Obviously it says to unlink something, but I don't know what it is linked to that it shouldn't be linked to.

Running as root seems to do something, but zsh still won't recognize the react-native command.

Add the admin permission to .npm home directory.

sudo chown -R $(whoami) ~/.npm
