Can not install in RaspberryPi

Hi,

The tool looks very interesting.

I've tried to install on my RaspberryPi OS but it fails with

Collecting git+https://github.com/vmassuchetto/shotwell-web-client.git

    Complete output from command python setup.py egg_info:

I wasn't able to figure out why, maybe you can help.
