I'm hoping there is some simple way like just copying the Python/Lib/site-packages folder, but I'm also guessing this isn't sufficient. I was hoping I wouldn't have to just one-by-one install all of those libraries again on the newer computer.

Make a list of the packages you need.  Put it in a file called 
requirements.txt.  Then install them with:

     $ pip install -r requirements.txt

Keep that file up-to-date as you add new requirements.
