ImportError with python-pptx

问题

I faced with problem when I installed python-pptx with conda on cleaned environment: conda install -c conda-forge python-pptx. After install was successfully finished I tried to import pptx module and got following error:

>>> import pptx
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\SazonovEO\AppData\Local\Continuum\anaconda3\envs\new\lib\site-p

    from pptx.api import Presentation  # noqa

    from .package import Package

    from .opc.package import OpcPackage
  File "C:\Users\SazonovEO\AppData\Local\Continuum\anaconda3\envs\new\lib\site-p

    from .oxml import CT_Relationships, serialize_part_xml

ackages\pptx\opc\oxml.py", line 12, in <module>
    from lxml import etree
ImportError: DLL load failed: Не найден указанный модуль.

But if I installed this library (python-pptx) with pip like this (also into new cleaned environment):

pip install python-pptx

this works. I have following versions: python version - 3.7.1, python-pptx-0.6.17, lxml-4.3.0.

Do you have any ideas about this issue?

回答1:

Reinstallation lxml from pkgs/main channel from anaconda repo allow workaround issue:

conda install lxml

The following packages will be UPDATED:

libxml2 conda-forge::libxml2-2.9.8-h9ce36c8_1~ --> pkgs/main::libxm l2-2.9.9-h464c3ec_0 libxslt
conda-forge::libxslt-1.1.32-heafd4d3_~ --> pkgs/main::libxs lt-1.1.33-h579f668_0

The following packages will be SUPERSEDED by a higher-priority channel: ... lxml
conda-forge::lxml-4.3.2-py37heafd4d3_0 --> pkgs/main::lxml- 4.3.2-py37h1350720_0 ...
