Bug: Can only run 1 docsify at a time

[jgraup]

First of all, docsify is awesome and so is this cli. My only problem is that I want to run multiple generated docs on various ports. When I specify a port other than the last docsify serve I am presented with an exception. This happens locally and on my remote server where I want many documents to co-exist. Locally I just want to be able to edit 1-2. Remotely I am pushing more.

Is there something I am missing to allow this to happen, or is this something that needs to be fixed.

The current work-around in my setup is to run a basic static nodejs server with forever.

Here is the error I am seeing after running docsify serve . --port 3000 then docsify serve . --port 4000:

Listening at http://localhost:4000

      throw er; // Unhandled 'error' event

Thanks in advance!

It looks like this issue is common: A, B, C.

Is it possible to support passing port info to livereload() as an extra argument?

--livereload-port 35730
