If you are familiar with pip, you may have tried
in the Leap IDE and noticed that it doesn't print out a list of the installed packages, as shown below.
We are working hard to bring this feature to you, but in the meantime try
pip --isolated freeze
This command lists system and user packages (whereas pip freeze just lists the user packages). When you use that command, you'll see a long list of all the packages installed, like in the image below.
