Here’s what I have done so far following the instructions on https://github.com/DefinitelyTyped/DefinitelyTyped#verifying.
I forked https://github.com/DefinitelyTyped/DefinitelyTyped.
I git cloned my fork and ran npm install.
I updated the type definitions and tests of types/markdown-to-jsx.
Now, running npm run lint markdown-to-jsx returns an error.
Why?
npm run lint markdown-to-jsx
> definitely-typed@0.0.3 lint /Users/sunknudsen/tmp/DefinitelyTyped
> dtslint types "markdown-to-jsx"
Error: Errors in typescript@next for external dependencies:
../react/index.d.ts(34,22): error TS2307: Cannot find module 'csstype'.
