無法在 cpython 3.8 中解析有效的 xml

Question

我正在嘗試在 Python 腳本中解析 xml 文件，該腳本在 C++ 應用程序中運行。 當我嘗試運行此腳本時：

import xml.etree.ElementTree as ET
root = ET.parse('somexml.xml' ).getroot()

我總是收到一個錯誤：

RunScriptFail: Traceback (most recent call last):
  File "xml\etree\ElementTree.py", line 1500, in __init__
  File "<frozen zipimport>", line 259, in load_module
  File "xml\parsers\expat.py", line 4, in <module>
ModuleNotFoundError: No module named 'pyexpat'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "xml\etree\ElementTree.py", line 1503, in __init__
ModuleNotFoundError: No module named 'pyexpat'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<string>", line 2, in <module>
  File "xml\etree\ElementTree.py", line 1202, in parse
  File "xml\etree\ElementTree.py", line 589, in parse
  File "xml\etree\ElementTree.py", line 1505, in __init__
ImportError: No module named expat; use SimpleXMLTreeBuilder instead

Error parsing script

但是 pyexpat.pyd 存在於 cpython 的 lib 文件夾中。 我該如何解決？ 或者我可以使用一些解決方法嗎？ 在 elementtree 中使用 SimpleXMLTreeBuilder 的解決方案對我有用

我發現需要的 pyexpat.pyd 沒有復制到分發中。 我添加了解決我的問題的廣告
