Elastalert startup error

[wenbingshen]

The following error occurred when I started the elastalert server
`> @bitsensor/elastalert@3.0.0-beta.0 start /opt/elastalert-server

sh ./scripts/start.sh

/opt/elastalert-server/src/index.js:1
import ElastalertServer from './elastalert_server';
^^^^^^

I guess the node.js dependent version of elastalert server is too low and many are already obsolete. Is there any way around this?I'm not familiar with node.js

The following warning occurred while I was building the docker image
