A few days ago I was doing a project in Python and wanted to let it practice for anyone who wanted to access it, and one of the steps for that was to build the requirements.txt, that commonly loads the necessary packages to run the projects in Python and the easiest alternative is:
- view the packages in the project;
- select the packages after executing:
$ pip freeze
But that's not practical at all, so I looked for an alternative that would meet my need, and found a project that did just that. Its goal is generate requirements.txt based on imports in project.
To install this package, just run:
$ pip install pipreqs --user
or, if you use Python3:
$ pip3 install pipreqs --user
To build automatically your requirements.txt, just run the following command in the project directory:
$ pipreqs
or
$ pipreqs /project/location
And the magic will happen!!
I hope this post helped and feel free to get in touch! ;)
Thanks for reading!
This post is inspired by the following repository:

pipreqs - Generate pip requirements.txt file based on imports of any project. Looking for maintainers to move this project forward.
pipreqs
- Generate requirements.txt file for any project based on imports
Installation
pip install pipreqs
Usage
Usage pipreqs [options] <path> Options: --use-local Use ONLY local package info instead of querying PyPI --pypi-server <url> Use custom PyPi server --proxy <url> Use Proxy, parameter will be passed to requests library. You can also just set the environments parameter in your terminal: $ export HTTP_PROXY="http://10.10.1.10:3128" $ export HTTPS_PROXY="https://10.10.1.10:1080" --debug Print debug information --ignore <dirs>... Ignore extra directories --encoding <charset> Use encoding parameter for file open --savepath <file> Save the list of requirements in the given file --print Output the list of requirements in the standard output --force Overwrite existing requirements.txt --diff <file> Compare modules in requirements.txt to project imports. --clean <file> Clean up requirements.txt by removing modules that are not imported in project. --no-pin Omit version of output packages.
Example
$ pipreqs /home/project/location Successfully saved requirements file in /home/project/location/requirements.txt
