在 Raspberry Pi 400 上为 python 安装 Adafruit_DHT 时出错

Question

我需要将 DHT-11 用于学校项目，但在尝试为其安装软件包时遇到了一个奇怪的错误。

按照我使用 sudo pip3 install Adafruit_DHT 的说明进行操作，结果如下：

sudo pip3 install Adafruit_DHT

      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

我也尝试运行sudo pip3 install Adafruit_DHT --install-option="--force-pi"，输出：

WARNING: Disabling all use of wheels due to the use of --build-option / --global-option / --install-option.

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

但是，当我运行我的 python 代码时，我得到了这个

  import Adafruit_DHT
ModuleNotFoundError: No module named 'Adafruit_DHT'

我已经更新了 pip 和设置工具，而且我对这一切都很陌生。这项任务很快就要到期了，我只想让这个 DHT 工作。提前致谢。
