title: Webpack and TypeScript: Module not found: Error: Cannot resolve 'file' or 'directory'
body: <p>I'm trying to compile TypeScript using Webpack, but for some reasons it fails on imports:</p>
  
  <blockquote>
    <p>ERROR in ./path/to/MySource.ts
        Module not found: Error: Cannot resolve 'file' or 'directory' ./path/to/MyIncludedFile in ...</p>
  </blockquote>
  
  <p>despite <code>MyIncludedFile.ts</code> is actually there and the IDE can recognise the import too, the TypeScript compiler doesn't find the file.</p>
