python - 我在 python 中使用 pyttsx3 时收到 "member not found"错误

Question

我正在使用 Visual Studio 2017 并创建一个 Python 应用程序。我在 python 中使用 pyttsx3 时收到“未找到成员”错误。该方法前几次被成功调用，然后调用错误，并且我无法进一步调用该方法。有人可以帮忙吗？

我尝试在 Python 3.6(64 位)和 Python 3.7(32 位)环境中更新 pyttsx3 模块。

我也尝试过“win32com module not found”问题中的答案。我仍然收到错误

def Say(text):
    try:
        speechEngine = pyttsx3.init()
        speechEngine.setProperty('rate', 150)
        print("{0} | Lola: {1}".format(TimeOfDay(), text))
        speechEngine.say(text)
        speechEngine.runAndWait()
        logging.info("Spoken words ({0})".format(text))
    except Exception as e:
        logging.error("Exception occurred", exc_info=True)
        print("{0} | Lola: {1}".format(TimeOfDay(),"I have come across an error in my code. See the log for details"))

预期的结果是它应该说出输出文本。但是，我收到以下错误:

我收到以下错误:

Exception occurred

   File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\lib\site-packages\pyttsx3\__init__.py", line 44, in init

在处理上述异常的过程中，又发生了一个异常:

Answer 1

我修正了错误。这是因为我在方法中一遍又一遍地调用 speechEngine = pyttsx3.init() 和 speechEngine.setProperty('rate', 150) (因为我有一个while 循环调用此方法)。我把它们搬到外面，效果很好。目前在任何时间后都没有看到错误。看看进展如何......
