Pyzbar modülünü çekemiyorum

Merhabalar,

import cv2

import pyzbar.pyzbar as decode

import os

capture = cv2.VideoCapture(1)

while(True):

    ret, image = capture.read()

    detectedBarcodes = decode(image)

    for barcode in detectedBarcodes:

        (x, y, w, h) = barcode.rect

        cv2.rectangle(image, (x, y), (x + w, y + h), (255, 0, 0), 5)

        cv2.putText(image, "Barkod Data: " + str(barcode.data), (0, image.shape[0] - 10),

                    cv2.FONT_HERSHEY_TRIPLEX, 0.5, (0, 0, 0), 1)

        #print(barcode.data)

        #print(barcode.type)

    cv2.imshow('Image with faces', image)

    if (cv2.waitKey(1) == 27):

        break

capture.release()

cv2.destroyAllWindows()

Hata nedeni nedir? Nasıl çözebilirim?
