grunt.jsをインストールしようとしています。公式ドキュメントが言うように、私は実行する必要があります
npm install -g grunt-cli
ルートとして(私はubuntu Linuxを使用しています)。私は試しています-そして、次のエラーが表示されます:
$ sudo npm install -g grunt-cli
npm ERR! sudon't!
npm ERR! sudon't! Running npm as root is not recommended!
npm ERR! sudon't! Seriously, don't do this!

npm not ok
誰か説明してください:
[1] why npm says `sudon't` and grunt docs says `do sudo`? And what is it all about?
[2] I want to install the grunt as a tool. Why does the message complains about missing package.json which is project-dependent (and I don't want to run grunt on any project, I want to install it globally first)?
[3] what can I do to make it install successfully?
