python - 我在运行一个简单的 pyttsx3 示例时遇到错误

Question

在 windows 和 rasbian 中分别使用 python 3.8 和 2.7 的 pyttsx3 的困难

当我试图运行一个简单的基本 pyttsx3 代码出错，请建议更换此软件包。我正在尝试开发个人助理，我需要 pyttsx3 模块才能工作。关于 的所有教程pyttsx3 它可以正常工作，没有任何错误，但使用 python 3.8 它会出错。我尝试在 Windows 和 raspbian 中使用这个包，两种情况下的错误都是一样的。

这是我正在尝试执行的一段代码，我已经安装了所有必要的模块 pywin32、pyttsx3、pyaudio、speechrecognition 一切。

import pyttsx3 
**engine = pyttsx3.init() 
engine.say('Hello sir, how may I help you, sir.')   
engine.runAndWait()** 

*it is giving error as:*

尝试使用较低版本的 pyttsx3。请执行下列操作:

pip uninstall pyttsx3
pip install pyttsx3==2.6
