AttributeError:模块“comtypes.gen.SpeechLib”没有属性“ISpeechVoice”

Question

我想在我的代码中使用pyttsx3，但是我总是有这样的错误：

Traceback (most recent call last):
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\pyttsx3\__init__.py", line 20, in init
    eng = _activeEngines[driverName]
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\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 "test3.py", line 3, in <module>
    engine = pyttsx3.init()
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\pyttsx3\__init__.py", line 22, in init
    eng = Engine(driverName, debug)
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\pyttsx3\engine.py", line 30, in __init__
    self.proxy = driver.DriverProxy(weakref.proxy(self), driverName, debug)
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\pyttsx3\driver.py", line 52, in __init__
    self._driver = self._module.buildDriver(weakref.proxy(self))
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\pyttsx3\drivers\sapi5.py", line 30, in buildDriver
    return SAPI5Driver(proxy)
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\pyttsx3\drivers\sapi5.py", line 35, in __init__
    self._tts = comtypes.client.CreateObject('SAPI.SPVoice')
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\comtypes\client\__init__.py", line 250, in CreateObject
    return _manage(obj, clsid, interface=interface)
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\comtypes\client\__init__.py", line 188, in _manage
    obj = GetBestInterface(obj)
  File "C:\Users\Romain\AppData\Local\Programs\Python\Python38\lib\site-packages\comtypes\client\__init__.py", line 112, in GetBestInterface
    interface = getattr(mod, itf_name)
AttributeError: module 'comtypes.gen.SpeechLib' has no attribute 'ISpeechVoice'

我的密码是：

import pyttsx3
engine = pyttsx3.init()
engine.say("This is a test")
engine.runAndWait()

你能帮帮我吗？(使用Python3.8.3和Studio代码)

Answer 1

我决定用另一个版本重新安装pyttsx3，它成功了(命令：pip uninstall pyttsx3和pip install pyttsx3==2.7)

Answer 2

这个问题是由于comtypes的旧版本(pyttsx3中所需的默认模块)而产生的，因此不需要安装旧版本的pyttsx3

只需在cmd中键入以下内容：

pip install --upgrade comtypes

现在你可以走了
