在Python3.8中安装Pdf2docx，始终无法安装成功，提示找不到模块_fitz

通过pip命令安装的Pdf2docx,但用import使用时提示如下：
Traceback (most recent call last):
File ““, line 1, in
File “C:\Users\zhy\AppData\Local\Programs\Python\Python38\lib\site-packages\pdf2docx_init_.py”, line 1, in
from .converter import Converter

from . import _fitz
ImportError: DLL load failed while importing _fitz: 找不到指定的模块。

重新安装fitz和PyMuPDF仍然无法解决问题。
