I wanna use the OpenCV and the camera module to recognize the qr code with Raspberry Pi3.
And I followed the article here, all the things are good until run "from pyzbar import pyzbar".
It shows the following text:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named pyzbar
I keep searching for the solution for this and I've runned the following instructions:
sudo apt-get install python-qrtools
sudo apt-get install libzbar-dev
sudo pip install zbar
but when I run the "sudo pip install zbar", it show this:

i think the error "Failed building wheel for zbar" will be the key of it, and i run the following instructions:
sudo apt install python-zbar
sudo apt install zbar-tools
after running, when i run "sudo pip install zbar", it still shows the same error. There's still no modules named pyzbar. Anyone know where the problem is?
