Angularfire2使用新的应用程序实例创建用户显示错误auth（）未找到

Question

我想使用angular和angularfire2插件创建多个用户帐户。

import Vue from 'vue'
import Router from 'vue-router'
...
const Products = () => import('@/views/products/Products')
Vue.use(Router)
export default new Router({
  mode: 'hash', // https://router.vuejs.org/api/#mode
  linkActiveClass: 'open active',
  scrollBehavior: () => ({ y: 0 }),
  routes: [
    {
      path: '/',
      redirect: '/pages/login',
      name: 'Home',
      component: DefaultContainer,
      children: [
        {
            path: 'products',
            redirect: '/products/sparepart',
            name: 'Products',
            component: {
                render (c) { return c('router-view') }
            },
            children : [
                ...
                {
                    path: 'products',
                    name: 'products',
                    component: Products,
                    props:true
                }
            ]
        },
      ]
    },
    {
      path: '/products/products',
      name: 'ProductsProducts', // just guessing
      component: {
          render (c) { return c('router-view') }
      },
      props: (route) => ({keyword: route.query.keyword}) // set keyword query param to prop
    }
  ]
})

当我运行此代码时，会返回错误

  

错误TypeError：secondaryApp.auth不是函数       在StaffAddComponent.push ../ src / app / layout / staff / add / staff-add.component.ts

方法定义看起来不错，但是代码无法正常运行。
