django - ModuleNotFoundError : No module named 'win32api' right after I install channels

我正在构建一个带有 WebSockets 和 django channel 的聊天应用程序。
我运行'pip install channels'它成功安装。然后我安装'asgi_redis'。这也被安装。现在，当我尝试导入 channels.asgi 时，它给了我错误。也突然我的 manage.py shell 停止工作。在其他 Django 项目中，它工作正常。

尝试访问 shell 时出错:

安装 channel 之前的一切似乎都运行良好。
设置.py:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'chat',
    'channels',]
CHANNEL_LAYERS = {
    'default': {
        'BACKEND' : 'asgi_redis.RedisChannelLayer',
        'CONFIG':{
            'hosts': [os.environ.get('REDIS_URL', 'redis://localhost:6379')],
        },
        'ROUTING' : 'chat.routing.channel_routing',
    },
}

点卡住:

引用这个帖子。收到该错误后，手动安装 pypiwin32 包。

pip install pypiwin32

即使您的 ide 无法识别要从中导入的 channel ，请忽略它并运行服务器。它会工作。
