Try: let g:tern#command = ['tern']

I know I might be a little late to answer this here... but just for the record:
No param:
let g:tern#command = ['tern']

To specify a host to listen on. Defaults to 127.0.0.1. Pass null or any to listen on all available hosts.:
let g:tern#command = ['tern', '--host xxxx']

To specify a port to listen on, instead of the default behaviour of letting the OS pick a random unused port:
let g:tern#command = ['tern', '--port xxxx']

What I use:
let g:tern#command = ['tern', '--no-port-file --persistent']

The following command-line flags are supported:
--port <number> Specify a port to listen on, instead of the default behaviour of letting the OS pick a random unused port.
--host <host> Specify a host to listen on. Defaults to 127.0.0.1. Pass null or any to listen on all available hosts.
--persistent By default, the server will shut itself down after five minutes of inactivity. Pass it this option to disable auto-shutdown.
--ignore-stdin By default, the server will close when its standard input stream is closed. Pass this flag to disable that behaviour.
--verbose Will cause the server to spit out information about the requests and responses that it handles, and any errors that are raised. Useful for debugging.
