导入错误：没有系统模块“pywintypes”（pywintypes39.dll）

Question

我正在用 python 制作虚拟助手，但我看到以下错误。

ImportError: No system module 'pywintypes' (pywintypes39.dll)

我使用的是 Windows 10 和 Python 3.9

这是代码

import speech_recognition as sr
import pyttsx3 
listner=sr.Recognizer()
engine=pyttsx3.init()
engine.say('Hello Vishal. I am Cisco')
engine.say('What do you want me to do?')
engine.runAndWait()
try:
    with sr.Microphone() as source:
            print('listening...')
            voice=listner.listen(source)
            command = listner.recognize_google(voice)
            command=command.lower()
            if "cisco" in command:
                 print(command)
except:
    print('Something went wrong')

另外，当我运行该程序时，控制台会打印以下内容：

    enter code hraceback (most recent call last):
  File "C:\Users\visha\AppData\Roaming\Python\Python39\site-packages\pyttsx3\__init__.py", line 20, in init
    eng = _activeEngines[driverName]
  File "C:\Program Files (x86)\Python\lib\weakref.py", line 134, in __getitem__
    o = self.data[key]()
KeyError: None

During handling of the above exception, another exception occurred:

ImportError: No system module 'pywintypes' (pywintypes39.dll)
PS C:\Users\visha\Documents\Python> ere

我是初学者所以我没有太多想法。在此先感谢您的帮助

Answer 1

在命令提示符下键入python -m site以获取站点包。现在导航到该site-package文件夹​​并转到pywin32_system32复制pythoncom39.dll并pywintypes39.dll

返回一步到site-package文件夹并获取win32并粘贴文件。

Answer 2

尝试卸载 pywin32 并再次安装，对我有用
