Could not find a declaration file for module 'ethjs'

[pedrouid]

Failed to compile because I got the following error message:
Could not find a declaration file for module 'ethjs'

I tried to install @types/ethjs but wasn't successful

I managed to work around it by adding an empty declaration to the root directory index.d.ts
declare module "ethjs";

But then I ended getting a different error that I couldn't fix:
Cannot use namespace 'IProvider' as a type.

The Typescript environment is generated using:
create-react-app APP_NAME --scripts-version=react-scripts-ts

Used the following tsconfig.json:

  "compilerOptions": {
    "baseUrl": ".",
    "outDir": "build/dist",
    "module": "esnext",
