该错误是由于找不到指定的文件夹路径而引起的。请确保您提供的图像文件夹路径是正确的，并且在运行脚本之前已经存在。

根据您的代码，您将图像文件夹路径设置为'home'。这可能是一个相对路径，如果是这样，请确保当前工作目录是包含该文件夹的文件夹。否则，您可以尝试使用绝对路径来指定图像文件夹路径。

另外，请注意，在调用`main`函数之前，您需要将代码放在一个名为`if __name__ == "__main__":`的条件语句块中。这将确保在作为脚本运行时才执行`main`函数。

以下是更新后的代码示例：

#!/usr/bin/env python3
import os
import sys
import cv2
from pyzbar import pyzbar

def main(image_folder_path, output_file_name):
    img_files = [f for f in os.listdir(image_folder_path) if f.endswith(('.png'))]
    qr_codes_found = []

    for img_file in img_files:
        img_path = os.path.join(image_folder_path,img_file)
        img = cv2.imread(img_path)
        barcodes = pyzbar.decode(img)

        for barcode in barcodes:
            if barcode.type == 'QRCODE':
                qr_data = barcode.data.decode("utf-8")
                qr_codes_found.append((img_file, qr_data))

    with open(output_file_name,'w') as f:
        for file_name,qr_content in qr_codes_found:
            f.write(f"{file_name}: {qr_content}\n")

if __name__ == "__main__":
    image_folder_path = '/path/to/your/image/folder'
    output_file_name = 'qr_codes_found.txt'
    main(image_folder_path,output_file_name)

请将`/path/to/your/image/folder`替换为您的实际图像文件夹路径。
