python - 使用 wand 图像错误读取 PDF 文件：wand.exceptions.DelegateError

Question

我想编写一个读取 pdf 文件的 python 代码并将其转换为按照本教程的图像： https ://www.youtube.com/watch?v=pf7OONW7l54和https://www.youtube.com/watch?v =jRUcMiXZt5Q

如此巧妙地编写这部分代码：

import io 
from PIL import Image 
import pytesseract
from wand.image import Image as wi 

pdf = wi(filename="pub.pdf", resolution = 300)#reading the pdf file

我有这个错误
