How to remove a Yeoman generator

npm uninstall -g [generator-name] might not fix the UNMET DEPENDENCY. If you won't mind to reinstall the affected modules:

1. cd to your npm directory (e.g. /usr/local/bin/node_modules)
2. rm -rf [generator-name]
3. npm cache clean
4. npm install -g [generator-name]

Generators are just normal npm modules, so you can remove it with

npm uninstall -g generator-[nameOfGenerator]
