The Python project automatically generates the requirements file for the current project

Using PIP freeze

$ pip freeze > requirements.txt

This approach is to list the entire package in the environment, if it is a virtual environment that can be used.
Normally we only need to export the requirements.txt of the current project, so we recommend Pipreqs.

Using Pipreqs

This tool is a good helper, can be scanned by the project directory, automatically discover the use of those class libraries, automatically generate a dependency list, only build project-related dependencies to Requirements.txt

Installation

pip install pipreqs

Use

Very simple to use PIPREQS path name
This goes directly to the project root, so yes./

pipreqs ./
