我正在尝试在运行 Ubuntu 12.04 的 Beaglebone 上运行 Node Arduino 库 [https://github.com/rwldrn/johnny-5]。但是，当我尝试运行示例程序（servo.js 或任何其他程序）时，控制台会吐出：

/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:

我尝试通过 npm (npm install serialport) 安装串行端口，但仍然遇到相同的错误。如何安装 serialport 以便它可以被servo.js 文件识别？

serialport是johnny-fiveand的依赖关系firmata，但由于firmata它本身是依赖关系，johnny-five我相信firmata会serialport从 johnny-5/node_modules 引用。

另请注意，这serialport需要 Python 2.x。

如果 npm 安装johnny-five正确，它应该已经将serialport.node 构建到johnny-five/node_modules/serialport/build/Release -你在那里看到了吗？

如果没有，请在新目录中尝试此操作

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

它成功了吗？将/home/rov/node_modules/johnny-5替换为您刚刚构建的克隆存储库。
