【问题描述】：

启动应用程序时出错

在启动应用程序时，它显示以下错误，我尝试了下面提到的在线修复，但没有一个可以请求建议和解决方案

node_modules/@types/graphql/subscription/subscribe.d.ts(17,12): error TS2304: Cannot find name 'AsyncIterator'.
node_modules/@types/graphql/subscription/subscribe.d.ts(29,12): error TS2304: Cannot find name 'AsyncIterable'.
node_modules/graphql-tools/dist/stitching/makeRemoteExecutableSchema.d.ts(3,109): error TS2304: Cannot find name 'AsyncIterator'.

根据谷歌结果尝试修复

将esnext.asynciterable 添加到tsconfig.json 将esnext 添加到tsconfig.json

但它们都没有奏效。 package.json

【问题讨论】：

你可以尝试升级 TypeScript 吗？我正在使用 2.9.1，它对我有用。如果这没有帮助，如果您也可以在此处发布您的 tsconfig.json 文件，如果可能会帮助下一个响应者，那就太好了。

【参考方案1】：

然后删除节点模块：-

npm install 
npm install --save graphql-subscriptions
npm install --save @types/graphql
npm install --save @types/ws

在 tsconfig.json 中添加以下内容

"compilerOptions": 
  "lib": [
     "esnext.asynciterable"
   ]

【讨论】：

你好 Shivendra Gupta，我已经安装了这些软件包，但它仍然返回相同的错误。

删除节点模块然后执行-> npm install

你在 tsconfig.json 中添加了 "compilerOptions": "lib": [ "esnext.asynciterable" ] 吗？

嘿 Shivendra Gupta，我尝试了上述步骤，现在出现以下错误

node_modules/@types/graphql/subscription/subscribe.d.ts(36,13)：错误 TS2304：找不到名称“AsyncIterator”。

【参考方案2】：

遇到同样的问题，添加

"lib": ["es2017", "esnext", "esnext.asynciterable"]

对我的 tsconfig.json 没有帮助，这令人沮丧。

我提出了很多建议，最终 Shivendra 的回答为我解决了问题。希望这将有助于其他人将来来到这里。
