Update: It worked after following steps mentioned in similar issue thread for windows. Steps:

1. clone the git repository locally.
2. Replace ‘quiverboard/dist/’ with ['quiverboard/dist/’] in setup.py
3. Installed with python setup.py install

The above problem got resolved. I faced another issue after the above steps, server was throwing 500 Internal server error while requesting /inputs url failing at code trying to jsonify list of files. Solution: Upgraded flask to 0.12 which adds the required jsonify(array) support.

Last issue faced was related to error while inferring input shape from model. Hardcoded the value single_input_shape = [200, 200] to make it work.

Glad you were able to resolve you issue!
