package installation problem on Windows

[bgs-v]

Following the instructions on the main readme, after running package install data-import-handler I receive the following error:

Neither --zk-host or --solr-url parameters provided so assuming solr url is http://localhost:8983.

I've tried specific versions and different PCs/installations of Solr, but get this on every windows PC I try it on.
