如何使用npm mp3进行wav [英] How to use npm mp3 to wav

问题描述

当尝试使用 npm mp3-to-wav 将 mp3 转换为 wav 时，控制台会返回

When attempting to convert an mp3 to wav using npm mp3-to-wav, the console returns,

"mp3到wav exec错误:saveForWav错误:路径必须是字符串.['C:\ Projects \ Weatherman \ meme.wav']"

"mp3 to wav exec err: saveForWav err: Path must be a string. Received [ 'C:\Projects\Weatherman\meme.wav' ]"

我相当确定我要喂的东西是字符串，所以我不知道问题出在哪里.可以在npm mp3-to-wav > https://www.npmjs.com/package/mp3-to-wav#2-usage ，这是我的代码.

I'm fairly certain what I'm feeding it is a string, so I have not a clue where the problem lies. npm mp3-to-wav can be found at https://www.npmjs.com/package/mp3-to-wav#2-usage and here's my code.

const Mp32Wav = require('mp3-to-wav');

new Mp32Wav("C:/Projects/Weatherman/meme.MP3").exec()

如何获取文件以接收目录路径，我的目录路径是否有问题?

How do I get the file to receive the directory path and is there a problem with my directory path?

推荐答案

您得到的错误不是来自"mp3-to-wav"，而是来自fs
路径没有任何问题

the err you get is not from 'mp3-to-wav' its from fs
there isnt any problem with your path

  class Mp32Wav {

      constructor(input_file_path, output_dir) {

        if (!utils.checkArgsNotNull(...input_file_path)) {
          throw new Error('err arguments')
        }
        output_dir = utils.judgeNotNull(output_dir) ? output_dir : utils.splitFileDir(input_file_path)
        this._input_file_path = input_file_path
        this._input_file_name = utils.splitFilename(input_file_path)
        this._output_dir = output_dir
        this._output_file_name = this._input_file_name.toString().replace(/\.mp3/i, '')
      }

正如您在其构造函数中看到的那样，他们忽略了区分大小写的

as you can see in their constructor they ignore case sensitive

.replace(/\.mp3/i, '')

我不使用Windows，但我认为使用path模块创建路径并检查其绝对路径将对您有所帮助

I don't use windows but I think it will be helpful for you to use path module to create your path and check if its absolute

Node.js path.isAbsolute()方法

https://www.w3schools.com/nodejs/met_path_isabsolute.asp

而且，w3c中的所有示例都在Windows中使用双\\插入\\

例如

console.log(path.isAbsolute('C:\\test\\demo_path.js')); //true
