Todos example application does not run after build

Hi all,
I’m trying to run the Todos example application after build but its not working.
I just did:

meteor remove-platform ios
meteor remove-platform android
meteor build .
tar -zxf todos.tar.gz
cd bundle/programs/server/
npm install
cd …/…
MONGO_URL=“mongodb://user:pass@” ROOT_URL=http://localhost:3000 node main.js

And in the console I see:

Note: you are using a pure-JavaScript implementation of bcrypt.
While this implementation will work correctly, it is known to be
approximately three times slower than the native implementation.
In order to use the native implementation instead, run meteor npm install --save bcrypt
in the root directory of your application.

But I cannot access http://localhost:3000

Best regards,
