Could not find a declaration file for module 'prop-types'

See original GitHub issue

I’ve created a new project using create-react-app-typescript and added the simple Formik example from the readme but I got a compile error right away:

error TS7016: Could not find a declaration file for module 'prop-types'.

I think this is due to the @types/prop-types package being included in Formik’s devDependencies and not dependencies. Based on the TypeScript publishing doc, it seems like including the dependency in dependencies would be an appropriate way to manage it and should resolve this issue. Unfortunately, non-TS projects would bring down the dependency, but the alternative is requiring TS projects to manage a dependency their code doesn’t depend on.
