python key 错误 : 'sapi5'

Question

以前曾问过此类问题，但是它对我不起作用，我在 python 3.8.1 上遇到错误

o = self.datakey KeyError: 'sapi5'

和

During handling of the above exception, another exception occurred: my code :TypeError: item 1 in argtypes passes a union by value, which is unsupported.

import pyttsx3
engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
print(voices)

以及我得到的错误:

。我可以做什么来修复它？

Answer 1

根据Using pyttsx3版本是2.6(页面标题)。我在 2.81 版本中遇到了与您相同的问题。

尝试使用 pip install -Iv pyttsx3==2.6 -U 安装版本 2.6，它为我解决了问题。
