《node.js安装wx-voice转换silk和mp3》要点：
本文介绍了node.js安装wx-voice转换silk和mp3，希望对您有用。如果有疑问，可以联系我们。

一、安装mingw，这里安装到D:\MinGw。

然后安装gcc,g++,

c:\> mingw-get install gcc

二、先安装 WxVoice：

$ npm install wx-voice --save

$ npm install wx-voice -g

$ wx-voice compile

三、转换：

保存为w.js

const WxVoice = require('wx-voice');
var voice = new WxVoice();
voice.on("error", (err) => {});

voice.encode(
       "mp3.mp3", "mp3_output.silk", { format: "silk" },       (file) => console.log(file));

执行：

M:\apacheWeb\214_jiqirenIpad>node w.js

M:\apacheWeb\214_jiqirenIpad\node_modules\wx-voice\index.js:352

            throw new Error("Silk SDK not found,make sure you compiled using co

mmand: wx-voice compile");

            ^
