节点.JS错误:使用模块 Audioconcat 时找不到 ffmpeg

Question

想要连接两个音频文件。 我使用了一个名为 audioconcate 的 npm，但是当我安装和配置以下代码时，我遇到了以下错误

Error: Error: Cannot find ffmpeg

ffmpeg stderr: undefined

这是我正在使用的代码：(所有音频文件也在同一文件夹中(

var audioconcat = require('audioconcat'(

var songs = [
  'a(1).mp3',
  'a(2).mp3',
  'a(3).mp3'
]
audioconcat(songs)
  .concat('all.mp3') 
  .on('start', function (command) {
    console.log('ffmpeg process started:', command)
  })
  .on('error', function (err, stdout, stderr) {
    console.error('Error:', err)
    console.error('ffmpeg stderr:', stderr)
  })
  .on('end', function (output) {
    console.error('Audio created in:', output)
  })

Answer 1

看起来你没有安装 ffmpeg，这是该软件包的要求。

要求

带有附加编译标志的 FFMPEG --enable-libass --enable-libmp3lame
