我正在我的覆盆子pi 3上运行raspbian。我正在尝试安装serialport模块，并且出现了许多错误。 pi @ raspberrypi：〜/ pmsensor $ sudo npm install --save serialport --fix-missing
这是我得到的： serialport@4.0.7 install / home / pi / pmsensor / node_modules / serialport node-pre-gyp install --fallback-to-build

你正确地想出了如何解决这个问题。使用raspberry pi人们通常以root身份运行（就像你一样），如果你想安装一个带root的二进制包（可能是任何包），你需要使用--unsafe-perm标志和npm。节点serialport文档有更多信息。
