title: Failed to import ng2-dragula with jspm
body: <p>I was trying to inject <a href="https://github.com/valor-software/ng2-dragula" rel="nofollow">https://github.com/valor-software/ng2-dragula</a> to Angular2 project ruled with JSPM package manager. But when I import it main boot.js file fails to compile... The only solution I'd found before was to move the project to webpack management. Are there any other solutions?</p>
