无法在 cpython 3.8 中解析有效的 xml

Question

我正在尝试在 Python 脚本中解析 xml 文件，该脚本在 C++ 应用程序中运行。当我尝试运行此脚本时：

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

我总是收到错误：

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 存在于 cpython 的 lib 文件夹中。我该如何解决？或者我可以使用一些解决方法吗？ Using SimpleXMLTreeBuilder in elementtree 的解决方案适合我

我发现需要的 pyexpat.pyd 没有复制到分发中。我添加了解决我的问题的广告
