由于我不熟悉构建Android应用程序，并且我的JavaScript代码已经可以运行，因此我想运行node.js代码，该代码与Android上的USB设备（Elgato Stream Deck）进行交互。我使用的设备是ODROID单板计算机。
我安装了node.js v8.11.3和通过Termux环境构建C所需的工具（clang，make，binutils）。之后，我安装了依赖于elgato-stream-deck-clean的npm软件包node-hid。安装和编译似乎成功。
# npm install elgato-stream-deck-clean

但是当我想运行我的代码时，似乎在搜索路径中找不到该库。

我的搜索路径是
# echo $LD_LIBRARY_PATH
/system/lib:/data/data/com.termux/files/usr/lib
# find /system/lib/ /data/data/com.termux/files/usr/lib -name *hid*
/system/lib/libhidcommand_jni.so
对我来说似乎没有生成.so文件，但是我不确定node.js是否需要此文件。
我该如何解决？
