Beaglebone (ARM)的序列节点误差

Question

我试图在运行Ubuntu12.04的Beaglebone上运行Node库https://github.com/rwldrn/johnny-five。但是，每当我尝试运行示例程序(servo.js或其他任何其他程序)时，控制台就会发出：

/home/rov/node_modules/johnny-five/node_modules/firmata/node_modules/serialport/node_modules/bindings/bindings.js:91
  throw err
        ^
Error: Could not locate the bindings file. Tried:

我尝试过通过npm (npm安装序列化)安装序列化端口，但仍然会遇到相同的错误。如何安装序列化端口，以便servo.js文件能够识别它？

Answer 1

serialport是johnny-five和firmata的依赖关系，但是由于firmata本身是johnny-five的依赖项，我相信firmata会从johnny/node_模块中引用serialport。

还请注意， requires Python 2.x。

如果npm正确安装了serialport.node，它应该将johnny-five/node_modules/serialport/build/Release内置到johnny-five中--您看到了吗？

如果没有，请在新目录中尝试此方法。

• $ git clone https://github.com/rwldrn/johnny-five
• $ cd johnny-five
• $ npm install

成功了吗？将/home/rov/node_modules/johnny-five替换为您刚刚构建的克隆回购。
