How to automatically create requirements.txt of your project in Python3

I know that there is a lot of information about this topic available in internet, but how of those examples really work?

TLDR:

install pipreqs
python3 -m  pipreqs.pipreqs --encoding utf-8 --force  /home/path/to/project   

It should create requirements.txt file

To install requirements use following command

pip3 install -r requirements.txt
