python - Youtube_dl : ERROR : YouTube said: Unable to extract video data

Question

我正在用 Python 3 制作一个小图形界面，它应该下载一个带有 URL 的 youtube 视频。
我用了youtube_dl模块。
这是我的代码:

import youtube_dl # Youtube_dl is used for download the video

ydl_opt = {"outtmpl" : "/videos/%(title)s.%(ext)s", "format": "bestaudio/best"} # Here we give some advanced settings. outtmpl is used to define the path of the video that we are going to download

def operation(link):
    """
    Start the download operation
    """
    try:
        with youtube_dl.YoutubeDL(ydl_opt) as yd: # The method YoutubeDL() take one argument which is a dictionary for changing default settings
            video = yd.download([link]) # Start the download
        result.set("Your video has been downloaded !")
    except Exception:
        result.set("Sorry, we got an error.")

operation("https://youtube.com/watch?v=...")

当我执行我的代码时，我得到这个错误:

ERROR: YouTube said: Unable to extract video data

我看到了 here那是因为它没有找到任何视频信息，我该如何解决这个问题？
