pdfkit [WinError 740] 请求的操作需要提升 python3

Question

我想在给定的 url 上将 html 页面最好地转换为 pdf。我试过 pdfkit 但它给了我 [WinError 740] 请求的操作需要提升。

import pdfkit
path_wkthmltopdf = "D:\\w.exe"
config = pdfkit.configuration(wkhtmltopdf = path_wkthmltopdf )
pdfkit.from_url("http://www.google.com", 'd:\\out.pdf', configuration=config)

输出错误：

n [42]: import pdfkit
path_wkthmltopdf = "D:\\w.exe"
config = pdfkit.configuration(wkhtmltopdf = path_wkthmltopdf )

pdfkit.from_url("http://www.google.com", 'd:\\out.pdf', configuration=config)

Answer 1

我也遇到过这个问题，我通过运行.exe解决了这个问题，运行后它会创建一个新的目录，进入这个目录然后bin dir你会在那里找到一个exe文件 C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe 因此，将“D:\w.exe”替换为代码中的上述路径即可

当我没有完成 wkpdftohtml 库的完整安装时，我遇到了这个问题。打开包装后，无需提升即可运行。
