问题描述
我当前的一个项目遇到了问题，该项目旨在将数据从传感器实时传输到平台。它是一个 DHT22 传感器，能够测量温度和湿度。一种可能性是将数据直接从 RaspBerryPi 传输到平台。为了做到这一点，我遵循了本教程：https://github.com/SAPDocuments/Tutorials/blob/master/tutorials/iot-express-3-configure-device/iot-express-3-configure-device.md。到目前为止一切顺利。
但是我在输入这个命令后遇到了一个问题：
npm install --save rpi-dht-sensor
152 warn enoent ENOENT: no such file or directory,open '/home/pi/Downloads/package.json'
153 verbose enoent This is related to npm not being able to find a file.
