“找不到‘异步’的类型定义文件。TS2688”

Question

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，我收到以下错误：

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此错误。为什么async 需要类型定义？为什么找不到呢？

我已经尝试删除 node_modules 和 yarn.lock 并执行 `yarn install`

我还尝试删除整个文件夹并再次克隆我的存储库（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上运行良好：

tsconfig.json

{
  "compilerOptions": {
    "noImplicitAny": false,
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,

    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react"
  },
  "include": ["src"]
}

我编辑了给我带来异步问题的文件（我删除了异步），但我一直收到同样的错误。

Atom Linter 在tsconfig.json 的开头给我一个错误，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' .

我很难过，因为我没有添加 graphql 作为依赖项（它肯定不在 package.json 中）。

这可能与你使用的node版本有关，最低版本应该是nvm 10.18，所以请确保你有正确的依赖关系。
