我有一个用create-react-app制作的react/typescript应用程序
当我尝试在我的计算机中yarn start时，我得到以下错误：
Failed to compile.
undefined
TypeScript error in undefined(undefined,undefined):
Cannot find type definition file for 'async'. TS2688
我不明白为什么会发生这种错误。为什么async需要类型定义？为什么它找不到它？
我已经尝试删除node_modules和yarn.lock并执行"纱线安装"`
我还尝试删除整个文件夹并再次克隆我的repo(并再次安装所有内容(。
奇怪的是，当我克隆repo:时，这在我的笔记本电脑中运行得非常好

我编辑了导致异步问题的文件(我删除了异步(，但我一直收到同样的错误。
Atom Linter在tsconfig.json开始时给我一个错误，如下所示：
Cannot find type definition file for 'async' .
Cannot find type definition file for 'graphql' .
Cannot find type definition file for 'isomorphic-fetch' .
我被难住了，因为我没有添加graphql作为依赖项(它肯定不在package.json中(。
这可能与您使用的节点版本有关。最低版本应该是nvm 10.18，所以请确保您有正确的依赖关系。
