Automatically create requirements.txt

Sometimes I download the python source code from github and don’t know how to install all the dependencies. If there is no requirements.txt file I have to create it by hands. The question is: Given the python source code directory is it possible to create requirements.txt automatically from the import section?

Answer

Use Pipenv or other tools is recommended for improving your development flow.

pip3 freeze > requirements.txt  # Python3
pip freeze > requirements.txt  # Python2

If you do not use a virtual environment, pigar will be a good choice for you.
