Freezing python pip dependencies with a requirements.txt

Assuming you have your virtual environment activated, you have several simple approaches depending on your dependency manager:

pip

pip freeze > requirements.txt

pip3

pip3 freeze > requirements.txt

If a virtual environment is active, pip is most certainly equivalent to pip3.

pipenv run

pipenv run pip freeze > requirements.txt
pipenv run pip3 freeze > requirements.txt

pipenv run spawns a command installed into the virtual environment, so these commands are equivalent to the ones run without pipenv run. Once again, it is assumed that your virtual environment is active.

poetry

poetry export -f requirements.txt --output requirements.txt
