ironpdf RuntimeError:未能创建。NET运行时

我正在使用ironpdf遵循pdf阅读器教程 this link

但我得到了这个错误:

---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)

    78 else:

    59 return dotnet_cli.resolve().parent

RuntimeError: Can not determine dotnet root

The above exception was the direct cause of the following exception:

我试着卸载ironpdf,但没有成功。。。

我正在使用 jupyter笔记本6.4.12 , python 3.10.6 和 ironpdf-2023.7.9 版本

我 成功地 已安装ironpdf pip

有什么办法解决这个问题吗?

这是我的代码:

from ironpdf import *

# Load existing PDF document
pdf = PdfDocument.FromFile("mypdf.pdf")

# Extract text and images from PDF document
all_text = pdf.ExtractAllText()
all_images = pdf.ExtractAllImages()

# Or, extract text and images from specific pages
page_2_text = pdf.ExtractTextFromPage(1)
for index in range(pdf.PageCount):
    page_number = index + 1
    images = pdf.ExtractBitmapsFromPage(index)

任何帮助都将不胜感激
