ng2-dragula: Cannot install ng2-dragula@1.1.7

I got this error message while trying to install version 1.1.7

npm ERR! ng2-dragula@1.1.7 postinstall: `npm run webdriver-update && typings install`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the ng2-dragula@1.1.7 postinstall script 'npm run webdriver-update && typings install'.
npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the ng2-dragula package,
npm ERR! not with npm itself.
npm ERR! Tell the author that this fails on your system:
npm ERR!     npm run webdriver-update && typings install
