pyttsx3初始化错误，不能使用pyttsx3

Question

在pyttsx3中使用.getproperty（'voices'）属性时，我遇到了一些问题。因此，我决定卸载它，然后使用PIP重新安装它，看看是否可以解决问题。

上一个指向当我出现.getproperty（'voices'）错误时的链接：Why do I get an error with pyttsx3 when I try to access the properties of the voice?

现在，当我再次使用PIP安装它时，我什至无法初始化它

import pyttsx3
engine = pyttsx3.init()

它出现此错误：

Answer 1

我希望您正在尝试从https://pypi.org/project/pyttsx3/安装pyttsx3。

您是否可以执行pip install pyttsx3而没有任何问题？您是否正在尝试从jupyter运行以上代码？如果是的话，请不要一次运行完整的代码，即以下代码

import pyttsx3
engine = pyttsx3.init()
engine.say("I will speak this text")
engine.runAndWait()

首先单独运行import pyttsx3，然后尝试一个接一个地编写代码。在不同的系统上运行时，我曾多次遇到类似的问题。我不知道为什么会出现此问题，但是上述步骤肯定可以解决该问题。

Answer 2

尝试以下方法：

engine = pyttsx3.init（'dummy'）
