How to get installed modules in Pycharm

Hi all.

I'm using Pycharm with many interpreters because every projects require different version's module or different settings.

(You can see this in the following image.)

And if I enter Preference -> Project Interpreter menu, then I can see every modules installed in a specific Python interpreter.

- Interpreter 1

- Interpreter 2

As you can see the above two images, the installed modules are different because those are installed in different python interpreter.

My question is how to download the library list installed to each python interpreter.

pip freeze > requirement.txt doesn't work. Because this returns libraries installed in basic python interpreter in my laptop.

Anyone knows how to download installed module & version list from a specific python interpreter in Pycharm? (or from using some command?)

Thanks.
