我正在使用 Visual Studio 2017 并创建一个 Python 应用程序。我在 python 中收到 pyttsx3 的“找不到成员”错误。该方法在前几次被成功调用，然后错误被调用，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。

我还尝试了“未找到 win32com 模块”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，又出现了一个异常：

我修复了错误。这是因为我在该方法中一遍又一遍地调用speechEngine = pyttsx3.init()（speechEngine.setProperty('rate', 150)因为我有一个while循环调用此方法）。我把它们移到外面，它奏效了。目前在任何时间后都没有看到错误。会看看情况如何......
