I'm seeing this now on Electron master:

$ electron-docs-linter docs --outfile=electron-api.json --version=1.7.0
$ electron-typescript-definitions --in=electron-api.json --out=electron.d.ts

error TS6053: File '/Users/z/electron/electron/node_modules/electron-typescript-definitions/test-smoke/electron/test/index.ts' not found.

error TS6053: File '/Users/z/electron/electron/node_modules/electron-typescript-definitions/test-smoke/electron/test/main.ts' not found.
error TS6053: File '/Users/z/electron/electron/node_modules/electron-typescript-definitions/test-smoke/electron/test/renderer.ts' not found.

Maybe a gitignore or npmignore issue...
