I suggest you to create a separate virtual environment running Python 3 for this app, and install all of the required dependencies there. Run in Terminal/Command Prompt:
https://github.com/mainadwitiya/CoVid-19-Tracker-Coronavirus-.git
python3 -m virtualenv venv
In UNIX system:
source venv/bin/activate
In Windows:
venv\Scripts\activate
To install all of the required packages to this environment, simply run:
pip install -r requirements.txt
and all of the required pip packages, will be installed, and the app will be able to run.
