Python将pdf转换为图像？

Question

所以我正在使用 Wand 尝试将 pdf 转换为图像

from wand.image import Image

with Image(filename="test.pdf") as img:
     img.save(filename="/temp.jpg")

with Image(filename="test.jpg") as img:
     img.resize(200, 150)
     img.save(filename="t.jpg")

但出于某种原因，我得到：

Traceback (most recent call last):
  File "C:\Users\Rafael\Desktop\k\pdf to image.py", line 3, in <module>
    with Image(filename="test.pdf") as img:
  File "C:\Python27\lib\site-packages\wand\image.py", line 2534, in __init__
    self.read(filename=filename, resolution=resolution)
  File "C:\Python27\lib\site-packages\wand\image.py", line 2601, in read
    self.raise_exception()
  File "C:\Python27\lib\site-packages\wand\resource.py", line 222, in raise_exception
    raise e
DelegateError: PDFDelegateFailed `The system cannot find the file specified.

' @ error/pdf.c/ReadPDFImage/798

我可以做些什么还是有另一种方法可以将 pdf 转换为图像？

原因可能是缺少 Ghostscript 安装。这是关于SO的类似问题
