Question

我正在编写一个小应用程序来使用覆盆子pi来监控某些温度。我希望能够远程启动或重新启动监视脚本。我通过SSH，cd连接到.py文件的目录，然后我“python temp_controller.py＆amp;”。这导致我输入错误的错误。 “来自w1thermsensor导入W1ThermSensor”。直接在Pi上从Thonny运行脚本时不会发生此错误。

“主要”文件。

我猜您在本地计算机上执行了类似pip install w1thermsensor的操作，对吗？您还需要在Raspberry pi上安装w1thermsensor依赖

Python脚本不会通过SSH运行，但会在本地运行
