"ERROR in ./src/vendor.ts" and "ERROR in ./src/main.ts"

Hey!

I've tried to launch the app as explained in the quick start, but when I tried npm start, I've got:

ERROR in ./src/vendor.ts
Module build failed: Error: Could not find the following rules specified in the configuration:

webpack: bundle is now VALID.

I also encountered few problems when doing npm install, but it was OK with a sudo npm install.

Thank you for your help! :)
