使用Node.js和Johnny-Five无法find模块'serialport'

我尝试使用Johnny-five和node.js来运行Leap Motion Controls的脚本。 现在，当我尝试运行脚本它说：（错误：找不到模块'serialport'）我试过npm安装-g串行端口它通过然后给我很多（错误）代码在红色。 我怎样才能解决这个问题 ？

D：>节点robotarm.js

module.js:338 throw err; ^ Error: Cannot find module 'serialport' at Function.Module._resolveFilename (module.js:336:15) at Function.Module._load (module.js:278:25) at Module.require (module.js:365:17) at require (module.js:384:17) at Board.Serial.detect (D:\node_modules\johnny-five\lib\board.js:70:7) at new Board (D:\node_modules\johnny-five\lib\board.js:303:23) at Object.<anonymous> (D:\robotarm.js:90:9) at Module._compile (module.js:460:26) at Object.Module._extensions..js (module.js:478:10) at Module.load (module.js:355:32)

然后我尝试

D：> npm安装serialport

它给

Answer 1

它告诉你，你所请求的版本不能作为你的平台的预build二进制文件。 串口访问是一个低层次的系统事物，所以这样的模块不能用纯Javascript编写。

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build软件包。 该模块是用C ++编写的，所以你必须安装Visual Studio Express。 构build脚本是用Python编写的，所以你必须安装Python。 或者与模块创build者交谈，问他为什么没有为你的平台准备好二进制文件（他有一个Gitter聊天室）。

Answer 2

问题解决了:)如果有人有问题。 安装Visual Studio，Python然后npm install serialport然后cd node_modules cd serialport node-pre-gyp rebuild cd serialport node-pre-gyp rebuild
