Pyttsx3 工作得更早，但现在不行了

Question

2019 年 12 月，我的 pyttsx3 模块工作正常，没有错误。几个月后，我卸载了 Python，但在 2020 年 5 月我再次安装了它。但这一次，奇怪的错误来了... 我的操作系统是win10Pro，Python 3.7(更近似的是一样的(，IDE是Pycharm。代码是：

import pyttsx3

def speak(text):
engine = pyttsx3.init()
engine.say(text)
engine.runAndWait()

speak("Hello World!")

当我运行它时：

我不明白。我做什么？如果你知道如何解决它，请与我分享。

这可能会有所帮助。你应该尝试安装Python的工具。我的意思是开发和其他依赖项。安装 python 开发工具的一种方法是apt-get install python-dev如果这不起作用，您将使用 python 版本做同样的事情。
