module collections has no attribute Hashable PyDocx 库报错

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：

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):
