Picamera2 and libcamera

I have a problem with picamera2. When I run the script, I get the following error:

   

Traceback (most recent call last):

File "<string>", line 2, in <module>

File "/home/pi/Projekt/lib/python3.11/site-packages/picamera2/ Init.py", line 4, in

odule>

import libcamera

ModuleNotFoundError: No module named libcamera

I am working on a Raspberry Pi Zero 2W. I am a beginner with Raspberry Pi. How can I solve this error?
