I've just installed the firebase-tools with the as usual npm package installation process :
npm install -g firebase-tools
i've already created a Firebase account connect with Google Account, but the problem is that the only procedure i can made with the command line tool is :
firebase login // with success
firebase prefs:token // return me the auth token
but every time i try the other commands i get the error :
Error: Authentication required.
for example for the command init, list etc :
firebase init // error
firebase list // error
and so on ... why ?
The version of npm, node and firebase-tools :
node : v4.2.2
npm : 3.3.12
firebase : 2.2.0
Use following command
1) firebase use --add
-> select project .firebaserc file has been created in your source dir
2) firebase deploy
now deploying hosting.
Thanks
