python - ImportError pyzbar macbook m1

问题描述

我正在使用 m1 Macbook Pro 并在使用 pyzbar 运行我的代码时遇到错误。我还下载了 pyzbar 和 zbar。我安装了自制软件并使用了 brew install zbar 和 pip3 install pyzbar

以下是完整的错误：-

    raise ImportError('Unable to find zbar shared library')
ImportError: Unable to find zbar shared library

以下是我的代码： -

from tkinter import*
from PIL import ImageTk,Image
import cv2
from pyzbar.pyzbar import decode

root=Tk()
root.title("Barcode Scanner")
root.configure(bg="tan4")
root.geometry("300x400")

vdo=Label(root)
vdo.grid(padx=10,pady=10)

cap=cv2.VideoCapture(0)

def readBarcode(frame):
    barcodes=decode(frame)
    txt.delete(0,END)
    for a in barcodes:
        x,y,w,h=a.rect
        a_info=barcode.data.decode('utf-8')
        cv2.rectangle(frame,(x,y),(x+w,y+h),(0,255,0),2)
        font=cv2.FONT_HERSHEY_DUPLEX
        cv2.putText(frame,a_info,(x-6,y-6),font,1.0,(0,0,0),1)
        txt.insert(0,a_info+" ")
    return frame

def video_stream():
    _,frame=cap.read()
    frame=cv2.resize(frame,(250,250))
    frame=cv2.copyMakeBorder(frame,10,10,10,10,cv2.BORDER_CONSTANT)
    frame=readBarcode(frame)
    cv2Image=cv2.cvtColor(frame,cv2.COLOR_BGR2RGBA)
    img=Image.fromarray(cv2Image)
    imgtk=ImageTk.PhotoImage(image=img)
    vdo.imgtk=imgtk
    vdo.configure(image=imgtk)
    vdo.after(1,video_stream)

txt=Entry(root,width=25)
txt.grid(pady=25)

video_stream()
root.mainloop()

请帮我解决这个错误，我还没有找到任何解决方案。
