python - Import pptx 时出错“ImportError: DLL load failed: The specified procedure could not be found.”

问题描述

我有一个与这个线程非常相似的问题，但是解决方案不能解决我的问题。我不断收到此错误。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Anaconda3\lib\site-packages\pptx\__init__.py", line 14, in <module>
    from pptx.api import Presentation  # noqa
  File "C:\Program Files\Anaconda3\lib\site-packages\pptx\api.py", line 15, in <module>
    from .package import Package

  File "C:\Program Files\Anaconda3\lib\site-packages\pptx\opc\oxml.py", line 12, in <module>
    from lxml import etree
ImportError: DLL load failed: The specified procedure could not be found.

在我最初安装 python-pptx 时，我使用了：

pip install python-pptx

这不像OP所说的那样在他的职位上为他工作。我已经使用 pip 卸载并重新安装，并得到相同的错误。我还尝试再次安装并获得：

Requirement already satisfied: XlsxWriter>=0.5.7 in c:\program files\anaconda3\lib\site-packages (from python-pptx) (1.1.2)

conda install lxml 将更新

但我仍然得到一个错误。当我运行 pip install lxml 我得到：

Requirement already satisfied: lxml in c:\program files\anaconda3\lib\site-packages (4.4.2)

所以我现在完全不知道该怎么做才能让它发挥作用。任何帮助深表感谢！蒂亚！

更新：我卸载python-pptx然后lxml然后只是做了pip install python-pptx，我认为它可能工作。

标签： pythonpiplxmlcondapython-pptx

解决方案

通过 pip install --upgrade lxml 将 lxml 升级到最新版本对我有用。
