Nuxt生成并且Firebase发出计时器警告

Question

我正在基于Firestore中的集合在Nuxt.js中动态生成路由。一切正常，但随后发出此警告。

根据this post的建议，我添加了以下代码段：

export default {
  hooks: {
    generate: {
      done(builder) {
        firebase.firestore.terminate()
      }
    }
  },
}

但是这会产生致命错误：

 FATAL  The client has already been terminated.                                                                                       23:39:58

这是我的路线方法，部分取自this question：

generate: {
    async routes() {
      const collection = await db.collection('restaurants').get();
      return collection .docs.map(x => `/restaurant/${x.title}`);
    }
},

仅当我添加了generate对象时才会出现此警告，因此我知道问题出在该区域。有什么建议么？

编辑：nuxt.config.js中的Firebase初始化代码>

import firebase from 'firebase/app'
import 'firebase/firestore'

const config = {
  apiKey: '',
  authDomain: '',
  databaseURL: '',
  projectId: '',
  storageBucket: '',
  messagingSenderId: '',
  appId: '',
  measurementId: ''
};
firebase.initializeApp(config);
const fireDb = firebase.firestore();

export default {
    generate :{...}
}

我正在基于Firestore中的集合在Nuxt.js中动态生成路由。一切都很好，但随后发出此警告。 ╭──────────────────────────────── ────────...

从plugins/firebase.js，您应该导出fireDb，并且可以导入任何组件并按如下所示使用该变量
