无法在 cpython 3.8 中解析有效的 xml

问题描述

我正在尝试解析 Python 脚本中的 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()

我总是收到一个错误：

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,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 的解决方案对我有用

解决方法

我发现所需的 pyexpat.pyd 没有复制到发行版中。我添加的广告解决了我的问题
