ios - Youtube dl 不是用 python 2 执行的

Question

我想执行 youtube dl 来下载视频。

这是我的代码：

struct YoutubeVideoInfo: Codable {
  let fulltitle: String
  let url: String
  let thumbnail: String
  let uploader: String
  
  static func getVideoInfo(from url: String) -> YoutubeVideoInfo? {
    guard let path = Bundle.main.path(forResource: "youtube-dl", ofType: ""),
          let json = executeCommand(command: path, args: ["-f mp4/best", "--dump-json", url]),
          let data = json.data(using: .utf8),
          let info = try? JSONDecoder().decode(YoutubeVideoInfo.self, from: data) else {
      return nil
    }
    
    return info
  }
}


func executeCommand(command: String, args: [String]) -> String? {
  let task = Process()
  
  task.launchPath = command
  task.arguments = args
  
  let pipe = Pipe()
  task.standardOutput = pipe
  task.launch()
  
  let data = pipe.fileHandleForReading.readDataToEndOfFile()
  guard let output = String(data: data, encoding: .utf8) else {
    return nil
  }
  
  return output
}

但它显示错误：
