Question

我是Angular和学习的新手：）

更新用户个人资料时，它会保存个人资料更改，然后我在signOut上收到错误消息，想知道是否有人知道什么可能触发此操作，请参见下面的代码...

ERROR TypeError: Cannot read property 'updateProfile' of null

    at SafeSubscriber.push../node_modules/rxjs/_esm5/internal/Subscriber.js.SafeSubscriber.__tryOrUnsub (Subscriber.js:207)

我要更新的代码...

updateUserProfile() {
  this.store.dispatch(new AuthActions.SetIsPending(true));

  this.store
    .pipe(select(fromRoot.getAuthenticatedUserInformation))
.pipe(take(1)) <-- added this
    .subscribe(user => {
      this.fireauth.authState
.pipe(take(1)) <-- added this
      .subscribe(profile => {
        profile
          .updateProfile({
            displayName: user.displayName,
            photoURL: user.photoURL
          })
          .then(() => {
            this.store.dispatch(new AuthActions.SetIsPending(false));
          })
          .catch(error => {
            this.store.dispatch(new AuthActions.SetIsPending(false));
            console.log(error.message);
          });
      });
    });
}

使用Angularfire2更新用户个人资料
