Импортировать FireBase / приложение раньше работало, теперь я получил ошибку (Firestore не является функцией)?

Question

Я использую React и Redux. Я импортировал базу данных с использованием импорта, показанного ниже:

import * as firebase from 'firebase/app'
import 'firebase/firestore'

Все работало, тогда я зафиксировал изменения и отправил их в GitHub. Мой коллега вытащил код и сказал мне проверить его, и он не работал. Я пытался запустить код, но не работает. Я изменил импорт на:

import * as firebase from 'firebase/firebase'
import 'firebase/firestore'

код работает сейчас. Если у кого-то есть идея, в чем причина этой ошибки, пожалуйста, помогите мне разобраться в этой проблеме.

Answer 1

Я удалил package-lock.json файл

Затем запустил npm install

Я получил это предупреждение

Я переустановил Firebase

npm install --save firebase

и проблема решена.Нет предупреждений или ошибок, и он снова работает, как раньше.
