youtube-dl无法在pycharm中正常工作

如何解决youtube-dl无法在pycharm中正常工作

我已经编写了这段代码来仅从youtube上的URL下载音频，但是某些链接不起作用

video_url = "https://www.youtube.com/watch?v=5yijULf4Hko" #  doesn't work for example
#video_url = "https://www.youtube.com/watch?v=gKK3Y6iDk_Q" #  does work

filename = "song.mp3"

options = {
    'format': 'bestaudio/best','keepvideo': False,'outtmpl': filename,'postprocessors': [{
            'key': 'FFmpegExtractAudio','preferredcodec': 'mp3','preferredquality': '251',}],}

with youtube_dl.YoutubeDL(options) as ydl:
    ydl.download([video_url])

当我尝试第一个链接时，程序将输出以下内容：

[youtube] 5yijULf4Hko: Downloading webpage

Process finished with exit code 1

我正在使用最新版本的pycharm（2020.2.1） 已经尝试更新youtube-dl 我试图在命令提示符下下载，并且成功下载了音频文件 youtube-dl -f 251 https://www.youtube.com/watch?v=5yijULf4Hko

起初以为这是版权方面的问题，但它也不适用于某些我确定未获得版权的网址

解决方法

我找到了解决问题的方法，但感觉我做错了， 我改变了这一行：

reboot

到

with youtube_dl.YoutubeDL(options) as ydl:
    ydl.download([video_url])

我只是使用了程序上命令提示符下的命令，但是我无法让python库像这样工作，如果有人知道如何正确解决这个问题，我将不胜感激

,

这是我编辑的简单脚本，对我有用，但是你们可以尝试

    @bp.route("/down",methods=['GET','POST'])
    def download_file():
    video_info = youtube_dl.YoutubeDL().extract_info(
    url=video_url,download=False
     )
    filename = f"{video_info['title']}.mp3"
    ydl_opts = {
            'format': 'bestaudio/best','keepvideo': False,'outtmpl': filename,'postprocessors': [{
                'key': 'FFmpegExtractAudio','preferredcodec': 'mp3','preferredquality': '192',}],}
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        info_dict = ydl.extract_info(video_url,download=False)
        video_title = info_dict.get('title',None)

    path = f'C:\\{video_title}.mp3'

    ydl_opts.update({'outtmpl':path})

    try:
        with youtube_dl.YoutubeDL(options) as ydl:
            ydl.download([video_url])
    except:
        os.system(f"""youtube-dl -o "{filename}.%(ext)s" --extract-audio -x --audio-format mp3 {video_url}""")

        return index()

html代码

    <form action="/down" method="post">
    <button>
    <a type="submit"><i class="fas fa-cloud-download-alt" style="color: white;"> MP3</i></a>
    </button> 
    </form>
