Question

npm installieren angularfire2 wird mit Fehler ELIFECYCLE

Meine Knoten Version ist 4.4.0 und Web-Treiber-Manager ist bei 9.0.0

npm ERR! Darwin 15.3.0 
npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "angularfire2" "--save" 
npm ERR! node v4.4.0 
npm ERR! npm v3.8.2 
npm ERR! code ELIFECYCLE 

npm ERR! angularfire2@2.0.0-alpha.12 postinstall: `typings install; webdriver-manager update` 
npm ERR! Exit status 1 
npm ERR! 
npm ERR! Failed at the angularfire2@2.0.0-alpha.12 postinstall script 'typings install; webdriver-manager update'. 
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 angularfire2 package, 
npm ERR! not with npm itself. 
npm ERR! Tell the author that this fails on your system: 
npm ERR!  typings install; webdriver-manager update 
npm ERR! You can get information on how to open an issue for this project with: 
npm ERR!  npm bugs angularfire2 
npm ERR! Or if that isn't available, you can get their info via: 
npm ERR!  npm owner ls angularfire2 
npm ERR! There is likely additional logging output above.
