假設您已經使用以下命令通過pip安裝了.NET 6.0 SDK和IronPdf:

 pip install ironpdf

您可能在執行Python腳本時遇到以下異常:

Exception has occurred: Exception
Failed to locate IronPdf.Slim.dll at 'C:\Users\Name\AppData\Local\Programs\Python\Python311/IronPdf.Slim'. Please see /troubleshooting/quick-ironpdf-troubleshooting/ for more information
  File "C:\Users\Name\OneDrive\Documents\IronPdfPythonNew\working\viewport.py", line 1, in <module>
    from ironpdf import *
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

解決方案

包含IronPdf.Slim的目錄可以如下指定:

import sys
# Set the path to include the directory containing the IronPdf.Slim files.
# Users can determine this location by running `pip uninstall ironpdf` and pressing `N` to view the installation path.
sys.path.append('/path/to/python/packages')
import sys
# Set the path to include the directory containing the IronPdf.Slim files.
# Users can determine this location by running `pip uninstall ironpdf` and pressing `N` to view the installation path.
sys.path.append('/path/to/python/packages')
PYTHON

例如

import sys
# Add the directory of the IronPdf installation to the path for module resolution.
# This should point to the root directory of where IronPdf is installed.
sys.path.append(r'C:\Users\lyty1\AppData\Local\Programs\Python\Python311\Lib\site-packages')

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
# Add the directory of the IronPdf installation to the path for module resolution.
# This should point to the root directory of where IronPdf is installed.
sys.path.append(r'C:\Users\lyty1\AppData\Local\Programs\Python\Python311\Lib\site-packages')

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")
PYTHON

原因

大多數第三方庫安裝在名為"site-packages"的目錄中,該目錄位於Python安裝目錄內或者在使用虛擬環境時位於虛擬環境目錄內。 此目錄是您的Python解譯器可訪問的。

IronPDF將安裝IronPdf.SlimIronPdf.Native.Chrome.Windows

具體位置可能會根據操作系統和您的Python配置而有所不同。
