Kibana Dev environment does not start

Hello,

Im triying to setup a Development Environment of the latest version of Kibana (following this steps: https://github.com/elastic/kibana/blob/master/CONTRIBUTING.md) and I have an error when I try to start a Kibana server with npm start:

$ npm start

kibana@5.0.0-snapshot start /home/dlumbrer/kibana
./bin/kibana --dev

The console write that and not moving or anything starts. The Elasticsearch server works well ("npm run elasticsearch") and launch an Elasticsearch at port 9200.

Is strange because I was working with a Development Environment on an old version of Kibana and I had no problem.

Thanks.

I solved this using the 4.5 branch, thanks.
