DataStore - 架构未初始化。 DataStore 将无法按预期运行

Question

我正在开发一个使用 AppSync 和来自 aws 的 graphql 的应用程序，但是每当我运行以下代码行 DataStore.start() 时，都会发生以下错误：

[错误] 数据存储 - 架构未初始化。 DataStore 将无法按预期运行。如果您安装了多个版本的 DataStore，则可能会发生这种情况。请看https://docs.amplify.aws/lib/troubleshooting/upgrading/q/platform/js/#check-for-duplicate-versions

我不知道还能做什么。我什至从 0 开始了一个应用程序，并且发生了同样的问题。我已经删除了 node_modules 文件夹并重新安装了所有内容，但它不会而且我想不出一种方法来映射可能的错误。下面是代码和包。

import Amplify, { API, Auth, DataStore, Hub, Storage } from 'aws-amplify';
import awsmobile from './src/aws-exports';
import awsapigateway from './src/aws-api-gateway';

Amplify.Logger.LOG_LEVEL = 'DEBUG';
Amplify.configure(awsmobile);
API.configure(awsapigateway);

DataStore.start()
.then(() => console.log('DataStore started'))
.catch(e => console.log('Error init datastore: ', e))
.finally(() => console.log('DataStore finally'));
