如何安装 python-poppler

Question

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。它发现了错误：

  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

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

我试过跑步

import pdf2image
from pdf2image import convert_from_path

它发现了错误：

PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?

Answer 1

这可能会对您有所帮助：

os.environ["PATH"] = r"{'path'}\poppler-21.11.0\Library\bin"

通过替换代码中的路径来包含这一行。
