node.js - 使用 Node.js 和 Johnny-Five 找不到模块 'serialport'

Question

我尝试使用 Johnny-five 和 node.js 运行脚本，使用 Leap Motion Controls。现在当我尝试运行脚本时它说:(错误:找不到模块'serialport')我尝试了 npm install -g serial-port 它通过然后给我很多(错误)代码红色。我该如何解决这个问题？

D:>node robotarm.js

module.js:338
    throw err;
          ^

Answer 1

它告诉您您请求的版本不能作为您平台的预构建二进制文件使用。串口访问是底层系统的东西，所以这样的模块不能用纯Javascript写。

如该模块的安装说明中所述(跳至“安装特殊情况”:

https://github.com/voodootikigod/node-serialport

您必须在您的机器上构建包。该模块是用 C++ 编写的，因此您必须安装 Visual Studio Express。构建脚本是用 Python 编写的，因此您必须安装 Python。或者与模块创建者交谈并询问他为什么没有适用于您的平台的二进制文件(他有一个 Gitter 聊天室)。
