How to freeze packages installed only in the virtual environment?

How to freeze packages installed only in the virtual environment, that is, without the global ones?

pip freeze -l > requirements.txt 

Make sure you are working in the virtaualenv before doing pip freeze -l.

Only local packages on virtual environment

pip freeze -l > requirements.txt # or --local instead of -l

Only local packages installed by the user on virtual environment

pip freeze --user > requirements.txt

Install whatever you need to freeze in your virtual environment, and then

pip freeze > requirements.txt

After that install the packages in the virtual environment that you do not want to freeze.
