導入 pptx 時出錯“導入錯誤：DLL 加載失敗：找不到指定的過程。”

Question

我有一個與此線程非常相似的問題，但是該解決方案並未解決我的問題。 我不斷收到此錯誤。

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.

在我最初安裝 python-pptx 時，我使用了：

pip install python-pptx

這並不像OP所說的那樣在他的職位上為他工作。 我已經使用 pip uninstall 並重新安裝，並得到同樣的錯誤。 我還嘗試再次安裝並獲得：

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 將更新

但我仍然收到錯誤消息。 當我運行 pip install lxml 時，我得到：

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

所以我現在完全不知道該怎么做才能讓它發揮作用。 任何幫助深表感謝！ 蒂亞！

更新：我卸載了python-pptx ，然后是lxml ，然后只是pip install python-pptx ，我認為它可能正在工作。

Answer 1

通過 pip install --upgrade lxml 將 lxml 升級到最新版本對我有用。
