导入 pptx 时出错“导入错误：DLL 加载失败：找不到指定的过程。”

Question

I have a very similar issue to this thread however the solution is not fixing my issue. I keep getting this error.

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\package.py", line 11, in <module>
    from .opc.package import OpcPackage

  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.

On my initial install of python-pptx I used:

pip install python-pptx

which is not working as the OP said was working for him in his post. I have used pip uninstall and reinstalled, and get the same error. I also tried to just install again and get:

Looking in indexes: website name was here

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

conda install lxml will update

but I still get an error. When I run pip install lxml I get:

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

So I'm completely lost right now about what to do to get this to work. Any help is much appreciated! TIA!

UPDATE: I uninstalled python-pptx and then lxml and then just did pip install python-pptx and I think it may be working.

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