ModuleNotFoundError：没有名为“azure”的模块

Question

我正在尝试在我的 Windows 开发机器上运行 this 示例代码。当我尝试运行simple_send_message.py 时，我收到以下错误消息

Traceback (most recent call last):
  File "msg.py", line 3, in <module>
    from azure.iot.device.aio import IoTHubDeviceClient
ModuleNotFoundError: No module named 'azure'

我看到couple of 线程讨论相同的问题，但不确定解决方案是什么。

任何指针，如何在 Windows 机器上解决这个问题？

Answer 1

检查安装

请使用以下命令检查您设备上的 Python 和 pip 安装：

python --version 或 python3 --version

pip --version

---

安装在目录下

如果一切顺利，试试这个： 尝试在你的项目目录中安装包，这里是azure。这可能会奏效。例如：

$ cd [Project-Folder]

pip install azure-iot-device

Answer 2

你能用 pip3 试试吗？

pip3 install azure-iot-device
