ImportError: No module named alembic.migration

I'm trying to use Appmon on my Linux machine. I did install all the dependencies by running

sudo -H pip install argparse frida flask termcolor dataset --upgrade

But I get the following error when I run it.

Any idea what is wrong?

~/Programs/appmon-master $ sudo python appmon.py
