定位 IronPdf.Slim.dll 失败

假设您已通过 pip 使用以下命令安装了 .NET 6.0 SDK 和 IronPdf：

 pip install ironpdf

执行 Python 脚本时可能会遇到以下异常：

Exception has occurred: Exception
Failed to locate IronPdf.Slim.dll at 'C:\Users\Name\AppData\Local\Programs\Python\Python311/IronPdf.Slim'. Please see https://ironpdf.com/troubleshooting/quick-ironpdf-troubleshooting/ for more information

解决方案

包含 IronPdf.Slim 的目录可按如下方式指定：

import sys
# This line should point to the root directory that contains the IronPdf.Slim folder.
# Users can determine this location by running `pip uninstall ironpdf` and pressing `N`.
sys.prefix = '/path/to/python/packages'

import sys
# This line should point to the root directory that contains the IronPdf.Slim folder.
# Users can determine this location by running `pip uninstall ironpdf` and pressing `N`.
sys.prefix = '/path/to/python/packages'

例如

import sys
# This line should point to the root directory that contains the IronPdf.Slim folder.
# Users can determine this location by running `pip uninstall ironpdf` and pressing `N`.
sys.prefix = r'C:\Users\lyty1\AppData\Local\Programs\Python\Python311'

from ironpdf import *

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Create a PDF from a URL or local file path
pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/")

# Export to a file or Stream
pdf.SaveAs("url.pdf")

import sys
# This line should point to the root directory that contains the IronPdf.Slim folder.
# Users can determine this location by running `pip uninstall ironpdf` and pressing `N`.
sys.prefix = r'C:\Users\lyty1\AppData\Local\Programs\Python\Python311'

from ironpdf import *

# Instantiate Renderer
renderer = ChromePdfRenderer()

# Create a PDF from a URL or local file path
pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/")

# Export to a file or Stream
pdf.SaveAs("url.pdf")

原因

大多数第三方库都安装在名为 "site-packages "的目录中，该目录位于 Python 安装目录中，或者如果使用虚拟环境，则位于虚拟环境目录中。这是 Python 解释器可以访问的目录。

IronPDF 将安装 IronPdf.Slim 和 IronPdf.Native.Chrome.Windows。

具体位置可能因操作系统和 Python 配置而异。
