如何在Balena上运行的raspberry pi 3上修复无效的ELF标头错误？

Question

我正在尝试使用rpio库转换Node.js应用程序，使其在本地模式下由Balena驱动的Raspberry Pi 3上运行。换句话说，我希望通过Nodejs + Docker + Balena来控制树莓派上的GPIO。

我的Dockerfile安装了rpio库作为依赖项提到的gcc-4.8支持。容器的构建没有任何问题。但是，当节点进程启动时，它将引发错误无效的ELF标头：

17:50:00 - error: uncaughtException: /usr/src/app/node_modules/rpio/build/Release/rpio.node: invalid ELF header

为了调试错误是否与平台架构有关，我在dockerfile和节点的应用程序代码中都添加了命令RUN uname -a。相应地返回以下内容：

(Dockerfile)Linux 96cbf2e6ef3d 4.14.68 #1 SMP Tue Nov 27 09:53:28 UTC 2018 armv7l GNU/Linux
(Node file) Linux 2cfca32 4.14.68      #1 SMP Tue Nov 27 09:53:28 UTC 2018 armv7l GNU/Linux

由于架构似乎匹配，我很难从这里弄清楚该怎么做。

Dockerfile
