我开始使用graphql服务开发离子应用程序，但是我在节点模块中遇到了一些问题，我该如何解决呢？

[14:32:44]  typescript: D:/ionic/node_modules/@types/graphql/subscription/subscribe.d.ts, line: 17 
            Cannot find name 'AsyncIterator'.

      L16:      subscribeFieldResolver?: GraphQLFieldResolver<any, any>
      L17:  ): AsyncIterator<ExecutionResult>;

[14:32:44]  typescript: D:/ionic/node_modules/@types/graphql/subscription/subscribe.d.ts, line: 29 
            Cannot find name 'AsyncIterable'.

      L28:      fieldResolver?: GraphQLFieldResolver<any, any>
      L29:  ): AsyncIterable<any>;

这是我的package.json

我是 java/android 新手，我正在尝试使片段活动并在我的片段“tab2”中实现适配器，但在 line(adapter.java) 中获取错误代码：

inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

我已经在尝试修复了。但仍然无法解决这个问题。那么，我的代码有什么问题？这是我的完整代码adapter.java :`

package com.yoga1215051164.fragment2.adapter;
