Error installing yeoman

Question

Installing Yeoman on my OSX machine results in the following error:

paulh16$ npm install -g yo
npm http GET https://registry.npmjs.org/yo
npm http 304 https:         


        

Answer 1

The npm command fails because you need to be root to edit files under /usr/.

You should properly configure npm, see this relevant SO answer:

$ echo prefix = ~/.node >> ~/.npmrc
