Poppler PDFInfoNotInstalledError

Question

作为使用Poppler进行PDF渲染和转换的一部分，我有以下代码，但执行代码时出现了以下错误。

错误消息：pdf2image.exceptions.PDFInfoNotInstalledError:无法以获取页数。poppler是否已安装并在PATH中？

我添加了Poppler路径作为环境变量，但错误仍然存在。

import tempfile,os
with tempfile.TemporaryDirectory() as path:
images_from_path = convert_from_path("C:\Users\mehak\OneDrive\Desktop\iffco.pdf")
index = 1
for image in images_from_path:
image.save("C:\Users\mehak\OneDrive\Desktop" + str(index) + ".jpg")
index += 1```

Answer 1

我按照这些步骤包括了path，它按预期工作。

新建或编辑此变量并提及您的路径。

Answer 2

您可以在此处找到解决方案。

pip install pdf2image

您只执行了上面的步骤。

以下步骤取决于您的计算机系统。

窗口

Windows用户将不得不为Windows构建或下载poppler。我推荐最新的@oschwartz10612版本。然后，您必须将bin/文件夹添加到PATH或在convert_from_path中使用poppler_path = r"C:pathtopoppler-xxbin" as an argument。

Mac

Mac用户将不得不安装poppler。

使用Brew:安装

brew install poppler

Linux

大多数发行版附带pdftoppm和pdftocairo。如果未安装，请参阅软件包管理器以安装poppler-utils。

平台独立器(使用conda(安装poppler:conda install -c conda-forge poppler安装pdf2image:pip install pdf2image
