如何解决如何安装 python-poppler

我从 https://github.com/oschwartz10612/poppler-windows/releases/tag/v21.03.0 下载了 poppler 并尝试在命令提示符中使用 pip install python-poppler 安装它。它捕获了错误：

  Running setup.py clean for python-poppler
Failed to build python-poppler
Installing collected packages: python-poppler
    Running setup.py install for python-poppler ... error

我已经解压了 python poppler zip 文件并将其放在当前路径中，但是单击文件夹并没有安装它，我该如何安装它？文件夹如下所示：

我试过跑步

import pdf2image
from pdf2image import convert_from_path
