“找不到‘async’的类型定义文件。TS2688”

Question

I have a react/typescript app made with create-react-app

When I try to yarn start in my computer i get the following error:

Failed to compile.

undefined
TypeScript error in undefined(undefined,undefined):
Cannot find type definition file for 'async'.  TS2688

I don't understand why is this error happening. Why would async need a type definition? And why is it not finding it?

I already tried removing node_modules and yarn.lock and doing `yarn install``

I also tried removing the whole folder and cloning my repo again (and installing everything again).

Curiously, this works perfectly fine in my laptop when I clone the repo:

tsconfig.json

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

I edited the file that was giving me the async problem (I removed async) and I keep getting the same error.

Atom Linter gives me an error at the start of tsconfig.json like this:

Cannot find type definition file for 'async' .
Cannot find type definition file for 'graphql' .
Cannot find type definition file for 'isomorphic-fetch' .

Im stumped because I didn't add graphql as a dependency (it is certainly not in package.json ).

这可能与您使用的节点版本有关，最低版本应为 nvm 10.18，因此请确保您具有正确的依赖项。
