TypeScript Version: 2.4.1

Code

// A *self-contained* demonstration of the problem follows...
import module = require('module-in-node_modules-with-jsdoc-annotations');

Compiling with commonjs module resolution, and the --allowJS and --checkJS compiler options.

Expected behavior:

1. Typescript should be able to "find" any modules that are installed (e.g. in "node_modules"), even if it doesn't have type definitions for them.
2. Typescript should be able to rely on jsdoc annotations within those modules for type checking and language services.

Actual behavior:

[ts] Cannot find module 'module-in-node_modules-with-jsdoc-annotations'.
