Hi, I'd like to use pyalpm and pycman in my project. I need to get the database. Unfortunately, when I run the code, I get an exception saying "data is not initialized". How to fix that?

Code (a segment) (imported: pyalpm pacman AUR argparse): db = pyalpm.get_localdb() pargs = db.get_pkg(dep) oargs = argparse.Namespace(package=False, quiet=False, info=0, listfiles=0) localInstalled = pycman.action_query.display_pkg(pargs, oargs) pyalpm.release()
