我一直聚合物峰会

看迈克尔Bleigh当我尝试

observers: ['autoAuth(user, statusKnown)], 

autoAuth: function(user, statusKnown) { 
    if(statusKnown && !user) { 
    this.$.auth.signInAnonymously(); } 
}, 


signIn: function() { 
    let google = new firebase.auth.GoogleAuthProvider(); 
    this.user.linkWithPopup(google); 
} 

它的工作原理就好上了一个新用户，但在旧的用户我其他帐户得到错误的凭据已在使用

尝试......

observers: ['autoAuth(user, statusKnown)], 

autoAuth: function(user, statusKnown) { 
    if(statusKnown && (user === null || Object.keys(user).length === 0)) { 
    this.$.auth.signInAnonymously(); } 
}, 


signIn: function() { 
    let google = new firebase.auth.GoogleAuthProvider(); 
    this.user.linkWithPopup(google); 
}
