Question

我的问题与this thread非常相似，但是解决方案无法解决我的问题。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

    from lxml import etree
ImportError: DLL load failed: The specified procedure could not be found.

在我最初安装的python-pptx上，使用了：

pip install python-pptx

这不起作用，因为OP在他的职位上表示正在为他工作。我已使用pip卸载并重新安装，并得到相同的错误。我还尝试重新安装并获得：

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

但是我仍然得到一个错误。当我运行pip install lxml时，我得到：

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

因此，我现在完全不知道该怎么做才能做。任何帮助深表感谢！ TIA！

更新：我先卸载了python-pptx，然后卸载了lxml，然后才卸载了pip install python-pptx，我认为它可能正在工作。

Answer 1

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

导入pptx时发生错误“导入错误：DLL加载失败：找不到指定的过程。”
