Python pyttsx3在启动时引发错误

如何解决Python pyttsx3在启动时引发错误

Python 3.6

有一个代码：

import pyttsx3
engine = pyttsx3.init()
engine.say("Hello World!")
engine.runAndWait()

在启动时，出现错误：

Traceback (most recent call last):
  File "C:\Users\andre\PycharmProjects\Ilona\venv\lib\site-packages\pyttsx3\__init__.py",line 20,in init
    eng = _activeEngines[driverName]
  File "C:\Users\andre\AppData\Local\Programs\Python\python36\lib\weakref.py",line 131,in __getitem__
    o = self.data[key]()
KeyError: None

During handling of the above exception,another exception occurred:

Traceback (most recent call last):
  File "C:/Users/andre/PycharmProjects/Ilona/main.py",line 2,in <module>
    engine = pyttsx3.init()

    eng = Engine(driverName,debug)

    token = self._tokenFromId(value)
  File "C:\Users\andre\PycharmProjects\Ilona\venv\lib\site-packages\pyttsx3\drivers\sapi5.py",line 80,in _tokenFromId
    tokens = self._tts.GetVoices()
_ctypes.COMError: (-2147200967,None,(None,None))

已安装Pywin32，pypiwin32和pyttsx3模块。

使用PyCharm。

该怎么办？

解决方法

打开命令提示符/终端，然后键入：

1. pip uninstall pyttsx3
2. pip install pyttsx3==2.71

如果这样不起作用，请用engine=pyttsx3.init()替换engine=pyttsx3.init('dummy')

,

1. pip uninstall pyttsx3
2. pip install -u pipenv
3. pipenv install pyttsx3 希望这行得通
