项目背景
在测试PyDocx代码时
```python from pydocx import PyDocX
html = PyDocX.to_html("test.docx") with open("test.html", 'w', encoding="utf-8") as f: f.write(html) ```
发生错误：
Traceback (most recent call last):

AttributeError: module 'collections' has no attribute 'Hashable'
原因
在 Python 3.3 之前的版本中，collections.Hashable 是存在的，但在 Python 3.3 及以后的版本中，它被移动到了 collections.abc 模块中。
解决方法
到路径
虚拟环境路径\Lib\site-packages\pydocx\util\memoize.py
到第24行左右
python
def __call__(self, *args):
if not isinstance(args, collections.Hashable):
# uncacheable. a list, for instance.
# better to not cache than blow up.
return self.func(*args)
if args in self.cache:
return self.cache[args]
else:
value = self.func(*args)
self.set_cache(value, *args)
return value
将
if not isinstance(args, collections.Hashable):
改为
if not isinstance(args, collections.abc.Hashable):
